ABSTRACT:
Ethylene-vinyl acetate copolymers are carboxylated by copolymerizing an alpha, beta-unsaturated carboxylic acid and/or anhydride thereof with at least one vinylidene monomer having the formula: ##STR1## wherein X and Y can be the same or different, and each represents hydrogen, chlorine, alkyl, acetoxy, carboxylic acid ester group or cyano; with an ethylene-vinyl acetate copolymer in the presence of a polymerization initiator in a reaction medium of a ketone compound or a mixture of a ketone compound and an acetic acid ester, wherein the reaction is conducted in a heterogeneous state.
