DEFINITION

Classification: 44/393

Copolymer of olefinically unsaturated hydrocarbon monomer and additional monomer (e.g., ethylene-vinyl acetate copolymers, etc.):

(under subclass 389) Compositions which are copolymers of a hydrocarbon monomer having an olefinic double bond and of one or more additional monomers.

(1) Note. Olefinic double bonds are carbon to carbon double bonds between acyclic carbons or alicyclic carbons.
