DEFINITION

Classification: 524/529

Solid polymer drived from ethylenic monomers only admixed with ethylenic monomer:

(under subclass 502) Subject matter which involves the mixing of an NRM and a solid polymer, which polymer has been derived from ethylenic monomers only and has been further reacted with an ethylenic monomer; or wherein a NRM is admixed with a solid polymer derived from ethylenic monomers only and a separate ethylenic monomer.

(1) Note. This and indented subclasses generally contain subject matter relating to graft and block copolymers.

(2) Note. Patents in this area are placed in the first subclass that provides for the solid polymer or ethylenic monomer. No distinction has been made as to whether the monomer is part of the substrate polymer or the superstrate monomer. No distinction has been made as to amounts of materials.

(3) Note. This and indented subclasses also contain those products and compositions derived from contacting of solid polymers from ethylenic reactants only with ethylenic materials wherein the ethylenic reactant interacts with the polymer without undergoing simultaneous or subsequent polymerization.
