DEFINITION

Classification: 525/87

Solid polymer other than graft or graft-type derived from nonaromatic plural ethylenically unsaturated reactant:

(under subclass 86) Subject matter wherein the mixture contains, in addition to the graft copolymer or graft-type copolymer, a nongrafted solid polymer derived from a plural ethylenically unsaturated reactant which is devoid of any aryl group (e.g., butadiene, etc.).
