DEFINITION

Classification: 508/468

Olefin or alpha, beta-olefinically unsaturated carboxylate is an additional monomer of the polymer (e.g., fumarate-ethylene or fumarate-acrylate copolymers, etc.):

(under subclass 466) Compositions wherein an olefin monomer or an alpha, beta-olefinically unsaturated carboxylate monomer forms a copolymer with the alpha, beta-olefinically unsaturated dicarboxylic monomer.

(1) Note. More than two discrete olefinic-ally unsaturated monomers may form terpolymers, etc.

(2) Note. The alpha, beta-olefinically unsaturated carboxylate is typically an acrylate.
