DEFINITION

Classification: 526/307.7

Oxygen atom is part of ester group derived from unsaturated carboxylic acid:

(under subclass 307.4) Subject matter wherein the copolymer

is derived from a monomer containing an ester group derived from a comonomer containing an ester group derived from an unsaturated carboxylic acid (e.g., a polymer from N-N-ditertiary butylacrylamide and methyl acrylate, etc.).
