DEFINITION

Classification: 508/475

Polymer of monocarboxylic acid ester of olefinically unsaturated alcohol (e.g., ethylene-vinyl acetate copolymer, etc.):

(under subclass 465) Compositions wherein the compound having plural -C(=O)O- groups is a polymer prepared from a monocarboxylic acid ester of an olefinically unsaturated alcohol.

(1) Note. The monomers are normally addition polymerized through the olefinic double bonds.

(2) Note. The polymers encompassed herein may be homopolymers or copolymers.

(3) Note. Vinyl acetate is a typical monocarboxylic acid ester of an olefinically unsaturated alcohol.
