DEFINITION

Classification: 526/319

(under subclass 72) Subject matter wherein an unsaturated monomer contains at least one carboxylic acid ester group.

(1) Note. This subclass does not require that an ester be prepared from the reaction of an acid and an alcohol. It is sufficient if the ester compound be identical in structure to a compound prepared by the replacement of a hydroxyl group by a carboxylic acid radical. Each carboxylic acid ester, no matter how prepared, is to be regarded as being the reaction product of a carboxylic acid and a replaceable hydroxyl group.
