Class 522
SYNTHETIC RESINS OR NATURAL RUBBERS -- PART OF THE CLASS 520
SERIES
Class Definition:
GENERAL SUMMARY OF SUBJECT MATTER WITHIN THIS CLASS
A. The following types of claimed subject matter are proper
for this class.
1. A claim drawn to a process of making a photopolymerizable
composition of reactant X plus photoiniator or
photosensitizer.
2. A claim drawn to a photopolymerizable composition of
reactant X plus photoinitiator or photosensitizer.
3. A claim drawn to a process of irradiating reactant X with
or without a photoinitiator or photosensitizer being
present.
4. A claim drawn to a photopolymerizable composition of
reactant X plus photoinitiator or photosensitizer and any
other material (e.g., filler, solvent, etc.).
In the types of subject matter (1-4 above), reactant X can be
a monomer, low molecular weight condensation or addition
product, or solid polymer. The sole proviso is that the final
product be a solid polymer as is required by the Class 520
Series of classes. When a claim so expressly states, a
monomer or polymer is considered to be a photoinitiator or
photosensitizer.
The recitation of a specified amount of photoinitiator or
photosensitizer is unnecessary for purposes of classification
in this class.
B. To be properly classified in this class, a compound must
have a photoinitiator or photosensitizer claimed in addition
to the monomer to be polymerized or the polymer to be
treated. For example, a claim drawn to a photopolymerizable
composition comprising an ethylenically unsaturated monomer
plus a photoinitiator is properly classified herein, whereas
a claim drawn to a substituted benzophenone autopolymerizable
composition is not properly classifiable in this class. The
requirement for proper classification is separateness of
monomer or polymer and photoinitiator or phtosensitizer. A
material described as being both a photoinitiator or
photosenitizer and a reactant and a separate monomer or solid
polymer is a proper composition for subclass 1 of this class.
Products which are the result of a wave energy process are
normally excluded from this class and are classified in other
areas of the 520 Series of clases. An exception to this would
be a situation wherein a further wave energy step is
contemplated and the formed product is an admixture with a
photoinitiator or photosensitizer.
A claim drawn to a specific photoinitiator such as a
benzophenone with no mention in the claim of the
functionality of the substance as a photoinitiator is
classified herein if the disclosure teaches the use of
benzophenone as a photoinitiator.
A combination of chemical process steps not involving wave
energy followed by a subsequent chemical reaction involving
wave energy is classified herein provided the product is
proper subject matter for the Class 520 Series.
Claims drawn to the utilization of wave energy to initiate a
chemical reaction followed by the application of heat are
proper for this class. For example, a process of partially
polymerizing a monomer of methylfluoroacrylate by wave energy
followed by treatment with heat to complete the
polymerization is proper for the Class 520 Series.
The utilization of wave energy to induce a chemical reaction
which thereby proceeds without the assistance of further wave
energy is considered to be proper subject matter for this
class; for example, a claim drawn to utilizing wave energy to
activate a peroxide in order to generate free radicals,
wherein the free radicals promote a chemical reaction is
classified herein.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
The step in a process claim utilizing wave energy is the
proper basis for classification purposes. For example:
A. A claim drawn to processes of polymerixing ethylene in
the presence of carbon black (DNRM) by wave energy is
properly classified in subclass 71, whereas a claim drawn to
polymerizing ethylene in the presence of wave energy followed
by treating the product with carbon black (DNRM) is properly
classified in subclass 189.
B. A claim drawn to treating polyacrylonitrile with vinyl
chloride in the presence of energy is properly classified in
subclass 124, whereas a claim drawn to treating a graft
polyacrylonitrile-vinyl chloride copolymer with wave energy
is properly classified in subclass 149.
C. A claim drawn to the process of making polyethylene by
polymerizing ethylene in the presence of wave energy followed
by chemically treating said product with halogen (with no
wave energy present) would be classified in subclass 189,
whereas a claim drawn to the process of reacting polyethylene
with halogen in the presence of wave energy following by the
addition of carbon black would be classified in subclass
133.
Classification in Class 522 is on the first solid polymer
prepared. For instance, a process of chemically modifying a
solid polymer derived from ethylene only, by sulfonating,
(nonwave energy process) and then subsequently reacting said
sulfonated polymer with elemental halogen using wave energy
is proper in subclass 133, since the first solid polymer
prepared is polyethylene. Subclass 132 does provide for a
halogenated polymer which is subsequently reacted in that the
language of the subclass is "contains" rather than "derived".
In subclass 154 the language is "derived" and therefore if a
halogenated polyethylene is treated using wave energy
classification in subclass 161 is proper since the first
solid polymer is prepared from ethylene.
A process of treating a solid polymer with wave energy
followed by the addition of a chemical reactant is presumed,
in the absence to the contrary to proceed entirely by wave
energy and is classified in this class subclasses 113-147;
however, a process of treating an irradiated polymer with a
chemical reactant is properly classified in Class 525.
Additionally a process of treating a reactant with wave
energy followed by adding a solid polymer and reacting
therewith is presumed in the absence of information to the
contrary to proceed entirely by wave energy and is classified
in this class.
A process of treating a preirradiated polymer (no wave energy
process step recited) is properly classified in Classes
523-525 when no further wave energy step is claimed. For
example, (1) a process of a mixed preirradiated polymer with
a DNRM is properly classified in Class 524, and (2) a process
for treating a preirradiated polymer with an ethylenic
monomer is properly classified in Class 525.
The combination of Class 204 wave energy step followed by a
Class 522 wave energy step is classified herein; for example,
a claim drawn to a process of utilizing wave energy to
synthesize a monomer which is subsequently polymerized in the
presence of wave energy is classified herein.
The utilization of wave energy to generate heat, whereby the
heat generates or induces a chemical reaction is not
considrered to be "a chemical reaction induced by wave
energy" and thus is not proper subject matter for Class 522.
The process, however, is proper in for the Class 520 Series
if a solid polymer is produced.
Class 204, Chemistry: Electrical and Wave Energy, appropriate
subclasses provide for producing a product of the type
provided for in the Class 520 Series by other than a wave
energy process. Class 204 is superior to the Class 520
Series; therefore, a patent claiming in the alternative a
process of preparing an organic compound and a synthetic
resin or natural rubber in the presence of wave energy is
classified for original purposes in Class 204 and
cross-referenced to the Class 520 Series. In the situation
where an alternative process claim is presented along with a
specific process claim to the synthetic resin or natural
rubber, there is no specific claim to the nonsynthetic resin
or nonnatural rubber species, and the process is directed to
wave energy, the same rule of original patent placement
applies. Any process step involving electrolysis, an electric
current, electro-osmosis, electrophoresis, an electrostatic
field, an electrical discharge, or a magnetic field and also
involving the preparing or treating of a synthetic resin or
natural rubber is proper for Class 204, even when the wave
energy step involved is subsequent to a Class 204 step.
Combinations of chemical process steps provided for by the
Class 520 Series (other than those involving wave energy) and
process steps falling within the definition of Class 204 are
proper for Class 204 when the Class 520 Series process steps
are preparatory to the Class 204 process steps and are proper
for the Class 520 Series when the Class 204 process steps are
preparatory to the Class 520 Series process steps.
Class 430, Radiation Imagery Chemistry: Process,
Composition, or Product Thereof, appropriate subclasses
provide for radiation sensitive compositions and elements and
for processes of exposing said composition or elements to
wave energy using an imagewise exposure technique. Class 522
provides for compositions and processes involving use of
radiation for polymerizing compositions having a
photoinitiator or photosensitizer or for modifying polymers.
Class 430 provides for compositions solely disclosed, or
claimed for radiation imagery. Compositions and processes
not involving radiation imagery, or disclosing both a
radiation imagery use, and another use are placed in Class
522 and cross-referenced to Class 430. Also, see Class 430
classification line for compositions with art claimed,
especially, multiple use (Class 430, III A 2a).
Schedule Outline of Class 522: The schedule is divided into
a number of parts, each of which is distinct and provides for
different types of subject matter. The following SEARCH THIS
CLASS, SUBCLASS is a breakdown of the major areas and
indicates the type of subject matter provided therein.
SEE OR SEARCH THIS CLASS, SUBCLASS:
1 generic subclass for the class.
2 through 5, for manipulative process areas which provide
for certain designated processes of preparing or treating a
polymer or compositions therefore. This area has no generic
subclass and therefore documents not covered under the ambit
of this subclass range are classified below on some other
basis.
6 through 70, for the specified rate-affecting material area
which provides for processes of preparing or treating
polymers or compositions therefor wherein a rate-affecting
material is utilized simultaneously with the wave energy and
wherein at least one rate-affecting material is designated by
at least one atom, e.g., a nitrogen-containing
photoinitiator, etc. This area is further subdiveded into
the following six subclass ranges.
7 through 30, for two or more rate-affecting materials, only
one of which need be specifically claimed.
8 through 10, for either (1) at least two rate-affecting
material containing a keto group which is not part of a ring
(e.g., benzophenone, etc.) or (ii) the combination of one
rate-affecting material containing a keto group which is not
part of a ring plus a rate-affecting material referred to as
a "photoinitiator or photosensitizer". The basic premise of
these subclasses is that a rate-affecting material identified
as a "photoinitiator or photosensitizer" is to be equated
with a rate-affecting material containing a keto group
wherein the keto group is not part of a ring.
11 for the combination of a rate-affecting material
containing a keto group not part of a ring plus a broadly
claimed rate-affecting material, other than "photoinitiator
or photosensitizer", e.g., the combination of a benzophenone
and a curing catalyst would be proper for this subclass,
etc.
12 through 23, for the combination of either (1) a
rate-affecting material containing a keto group not part of a
ring plus a rate-affecting material wherein at least one atom
is designated; or (2) a rate-affecting material referred to
as a "photoinitiator or photosensitizer" plus a
rate-affecting material wherein at least one atom is
designated. The basis of classification in these subclasses
is with the latter ingredient of the aforementioned
combinations (1) and (2).
24 through 30, for the combination of two or more
rate-affecting materials neither one of which contains a keto
group not part of a ring. The basis of classification in
these subclasses is with the first appearing rate-affecting
material provided in the schedule hierarchy.
31 through 70, for specified rate-affecting material.
71 through 86, for the designated nonreactant areas provide
for processes of preparing or treating polymers or
compositions therefor, wherein a designated nonreactant
material is present when the wave energy is applied.
87 through 189, for the polymer preparation or treatment
area which provides for processes or compositions therefor of
the following six categories.
87 through 108, specifically for proteins and carbohydrates
as reactants and for treating a terminally unsaturated
polyurethane, ethylenically unsaturated siloxane,
polysiloxane, polyester or polypoxide derivative.
109 and 110, for chemically modifying a blend of two or more
solid polymers by a chemical reactant.
111 and 112, for treating a blend of two or more solid
polymers.
113 through 147, for chemically modifying a solid polymer by
a chemical reactant in the presence of wave energy.

a carbon atom is considered to be too broad. An exemplary
list of materials to be regarded as DNRM's is as follows:
metal hydrate, chalcogen, carboxylic acid, peroxy, peroxide,
latex, alkali or alkaline earth metal, transition metal,
halogen, proten donor, sulfiede, drying oil, fat, fatty acid
or ester, water, carbon black, etc. This list is by no means
limited to the above examples.
The following list is not exhaustive and merely enumerates
certain materials that will not be considered as DNRM's,
e.g., organic compound, metal containing, inorganic compound,
organometallic compound, solvent, wax, magnetic, hydrophobic,
hydrophillic, antiplasticizer, plasticizer, filler,
preservative, antioxidant, antiozonant, stablizer, lubricant,
fibrous additive, particulate additive, liquid, solid, gas,
dispersant, emulsifier, crystalline, plastic, flourescent,
phosphorescent, liminescent, deliquescent, drier, dessicant,
humectant, blue color, numerically described without
providing a chemical atom, Lewis acid or base, mineral,
organic solvent, cosolvent, Ziegler or Natta catalysts, alfin
catalyst, free radical, amphoteric, anionic, ionic,
denaturant, electrostatic, dielectric, conductor, insulator,
etc. This list is to be regarded as illustrative rather than
exhaustive.
WAVE ENERGY
The term "wave energy" includes radiations as well as wave
energies transmitted by various mediums and embraces
electromagnetic waves or radiations, ultrasonic and
supersonic waves, nuetrons, protons, duetron, and other
corpuscular radiations.

(1) Note. This area provides for a specific wave energy
process, i.e., laser. In order for a wave energy process to
be classified herein as an original, there must be a claim to
the noted process or the total disclosure in the patent must
be directed to the specific process. The wave energy process
in the claim need not be limited to the provided specific
process if the claim specifically recites the process of this
subclass. Processes not claimed or solely disclosed are

material or directional orientation; or compositions
therefor.
(1) Note. The steps of mixing, stirring, agitating, movement
of material or directional orientation must involve a direct
relationship with wave energy and not be ancillary to the
wave energy exposure. For instance, mixing two ingredients
under specific conditions to merely form a composition which

(1) Note. The two sources or energy maybe utilized in any
manner, e.g., successive, or concurrent, etc. Each of the
energy sources must cause a chemical reaction of its own
right or must potentiate, accelerate, or have a synergistic
affect in regard to the chemical reaction involved.
(2) Note. This subclass also provides for those
compositions perfected so as to be utilized in a process
involving the requirements or this subclass.
(3) Note. "Distinct" as used in this subclass includes the
same type of energy either derived from one or more sources
when said energy is used at different energy levels or wave
length levels. It also includes the same type of energy
derived from two different generating sources.

involving a temperature less than 0xC (32xF) or greater than
250xC (482xF); or compositions therefore.
(1) Note. The temperature conditions required must involve a
direct relationship with wave energy. For instance treatment
of a material by wave energy and subsequent physical
treatment at the temperature lower than 0xC is not proper
subject matter for this subclass.
(2) Note. A process performed while "frozen" or under
"cryogenic" conditions will be placed herein unless there is
a disclosure that the temperature is greater than 32xF.
(3) Note. This subclass also provides for those compositions
perfected so as to be utilized in a process involving the
requirements of this subclass.
Subclass:
6
Compositions to be polymerized or modified by wave energy
wherein said composition contains at least one specified
rate-affecting material; or processes of preparing or
treating a solid polymer utilizing wave energy in the
presence of a least one specified rate-affecting material,
e.g., nitrogen containing photosensitizer, oxygen containing
photoinitiator, etc.:
This subclass is indented under subclass 1. Subject matter
wherein said process or composition to be polymerized or
modified requires, in addition to the wave energy source, at
least one specified rate-affecting material.
(1) Note. A rate-affecting material is a material which
either affects the rate of reaction, permits reduced amount
of wave energy, increases or decreases the degree of
polymerization, cure, cross-linking, or grafting, or
scavenges or provides storage stability of reactive materials
or inhibits reaction; and includes photoinitiator,
photosensitizer, activator, dark storage stabilizer,
accelerator, inhibitor, or initiator reducing agent,
retarder, photoreducible dye, sensitizing auxiliary, electron
donor, generator, or curing catalyst.
(2) Note. A curing agent is presumed to be a cross-linking
agent and is not considered to be a rate-affecting material.
A curing catalyst, on the other hand, is considered to be a
rate-affecting material.
(3) Note. A specified rate-affecting material is a
rate-affecting material (see (1) Note) wherein at least one
of the chemical atoms can be deduced with certainty. The
following are examples of specified rate-affecting materials:
benzophenone, oxygen containing curing catalyst, and a metal

rate-affecting materials which are not specified: a metal
containing rate-affecting material, an organic containing
rate-affecting material, an inorganic catalyst, an
organometallic catalyst, a Lewis acid or base catalyst, a
Ziegler catalyst.
(4) Note. A compound not claimed although solely disclosed
as a rate-affecting material is considered to be a proper
specified rate-affecting material. For example, a claim
drawn to a process of preparing a solid polymer in the
presence of wave energy and a metal oxide is disclosed as
functioning in a catalyst capacity.
(5) Note. Unless disclosed to the contrary, a benzophenone
or derivative thereof is presumed to be a specified
rate-affecting material though not claimed or disclosed as
having catalytic activity.
