DEFINITION

Classification: 528/392

(under subclass 1) Subject matter under Class 520, ... involving polymers derived from at least one ethylenically unsaturated reactant and at least one non-ethylenically unsaturated reactant or processes of polymerization; polymerizable compositions containing at least one ethylenically unsaturated reactant and at least one nonethylenically unsaturated reactant or processes of preparing.

SEE OR SEARCH THIS CLASS, SUBCLASS:

480+, for processes of preparing a polymer not involving a chemical modification of the polymer, by the addition of a material thereto, and for chemically modifying material other than the polymer. Subclasses 480+ also provide for processes of admixing with a broadly claimed nonreactant material.

SEE OR SEARCH CLASS

525, Synthetic Resins or Natural Rubbers, appropriate subclasses for processes of chemically reacting a solid polymer.

526, Synthetic Resins or Natural Rubbers,

72+, for processes of polymerizing an ethylenic monomer in the presence of an ethylenic material, which ethylenic material concurrently enters into the polymer by reaction with a functional group of the ethylenic monomer and for processes of polymerizing ethylenically unsaturated monomers only.
