Class 526 provides for all processes of preparing polymers
from only ethylenically unsaturated monomers and for all products
thereof when such products and processes are not provided in higher
subclasses in the Class 260 schedule hierarchy.
In addition, Class 526 provides for certain polymerization
processes which are applicable to any type of reactant or monomer.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A. The following rules apply to claim classification in the
area encompassing subclasses 72 through 352.2 of this class.
(1) For purposes of clarification in this schedule, subclasses
59-238 will be deemed to be process subclasses, and subclasses 239-352.2
will be indicated as being product subclasses.
(2) Patents that claim a product and process, wherein both
the product and the process are specifically provided for in the
schedule, are classified in the process area (59-238) and cross-referenced
to the product area (239-352.2).
(3) Patents that claim a provided for process (59-238) and
a nonprovided for process (other than 89) but where the monomers
being polymerized are provided (239- 352.2) are classified in the
process area (59-238) and cross-referenced into the product area
on the basis of the first appearing monomer in the schedule that
is being polymerized (239-352.2).
(4) Patents that claim both a provided for (239-352.2) product
and a process of polymerizing (59-238) and wherein the product is
claimed in process terms are classified on the basis of the process
(59-238) and cross-referenced to the first appearing monomer in
the schedule utilized in preparing the polymer.
(5) Patents that claim a product solely in process terms are
classified on the basis of the process (59-238) when said process
is provided in the schedule and cross-referenced to the first appearing
monomer in the schedule utilized in preparing the polymer.
(6) Patents that claim a product in process terms and wherein
the process is not provided in subclasses (59-238) are classified
on the basis of the first appearing monomer in the schedule utilized
in preparing the polymer.
(7) Patents that claim a polymerizable composition or the
preparation of a polymerizable composition are classified on the
basis of the first apearing monomer (239-352.2) in the schedule
that is part of the polymerizable composition.
(8) Patents that claim a polymer only are classified on the
basis of the first appearing monomer in the schedule (239-352.2)
that has been polymerized in preparing the polymer.
(9) Patents that claim merely vulcanizing, curing, or cross-linking
of a polymer proper for this area, without the presence of a specified
vulcanizing, curing, or cross-linking agent, or the amount of the
chemical agent or the vulcanized, cured or cross-linked product
of such a reaction are classified on the basis of the first appearing monomer
in the schedule (239-352.2) that has been polymerized in preparing
the polymer.
(10) Patents that claim a polymer which is the result of a
degradation of a polymer proper for this area (239-352.2) and wherein
the degradation has been effected in the absence of any chemical
agent are classified on the basis of the initial first appearing
monomer in the schedule (239-352.2) that has been polymerized in
preparing the previously-formed polymer that is degraded.
(11) Each product subclass, subclasses 239-352.2 unless specifically
limites in its title, includes homopolymers and interpolymers.
(12) "Interpolymerized" as used throughout
the product area subclasses 239-352.2 includes all combinations
of the necessary monomers as required in the definition of the particular
subclass in combination with any other monomer not provided for
in a higher subclass of the schedule.
(13) A monomer for purposes of this subclass is a material
which occurs in a polymer as a repeating unit and is present in
at least three units and as used herein "monomer" is
meant to exclude catalyst residues, chain transfer agents, etc;
however, a nonethylenic carbohydrate or nonethylenic protein which
is present during polymerization of an ethylenic monomer and which
is described as chemically bonded to the polymer is proper subject matter
for Class 527, subclasses 313+.
(14) This subclass provides for processes wherein an ethylenically
unsaturated monomer is undergoing polymerization and concurrently
therewith is reacting with a second ethylenic material, which second
ethylenic material does not enter into the polymer backbone, e.g.,
polymerizing acrylic acid in the presence of allyl alcohol so that
the final polymer is a polymerized acrylic acid having ester groups
which are derived from the unsaturated alcohol.
(15) The sole requirement for the products of this subclass
is that the polymerization reaction involve only ethylenic unsaturated
monomers. Note, however, that the actual polymerization mechanism
need not involve the ethylenically unsaturated group (e.g., polymerization
of a glycidyl methylacrylate may involve the double bond in one
instance and in another instance may involve the ring opening of
the epoxy group, etc.).
(16) The treatment of a liquid polymer derived from an unsaturated
monomer which is to be further polymerized is regarded as involving
polymerization rather than as an after-treatment of a polymeric
polymer and is therefore classified in this area as against the
chemical after-treatment area, Class 525, subclasses 326.1+.
(17) In subclasses 239-352.2 each indent of a specific form
of "from monomer" only refers to species of that type
monomer and not to other monomers that may be interpolymerized therewith.
When other monomers which are not species of the "from
monomers" are to be taken into account the subclass has
been identified as "interpolymerized."
B. The following are lines relating to special subclasses:
(1) Subclasses 218.1+, 219.3+, 219.6
(1)
Note. A patent which recites a polymerization process which
utilizes (a) a material proper for subclasses 218.1+ in
combination with either a specified or nonspecified amount of "hydrocarbon
or halohydrocarbon" will not be classified in subclass
219.3 or its indents, but will be found in 219.6 or 218.1+;
proper, however, for subclass 219.3 or its indents is the situation
wherein when either the hydrocarbon or halohydrocarbon is defined
in some degree (e.g., dihalogenated, dibrominated, contains specified
chain length, boiling or freezing point range, etc.); (b) a "free
radical" catalyst with either a specified or nonspecified amount
of "hydrocarbon or halohydrocarbon" will be classified
with the polymer providing this was the only remaining basis for
classification.
