ABSTRACT:
An emulsion of a quarterly vinyl acetate-ethylene copolymer emulsified in an aqueous medium, is provided. The quarterly copolymer comprises: 100 parts, by weight, of a vinyl acetate-ethylene copolymer prepared from 95 to 60 parts, by weight, of vinyl acetate monomer (I) and 5 to 40 parts, by weight, of ethylene monomer (II); 0.5 to 7 parts, by weight, of an acid monomer (III) selected from the group consisting of monobasic unsaturated carboxylic acids each having 3 to 17 carbon atoms, dibasic unsaturated carboxylic acids each having 3 to 17 carbon atoms, anhydrides of said dibasic unsaturated carboxylic acids and semi-esters of said dibasic unsaturated carboxylic acids each having an alkyl chain of the alcohol part having 1 to 10 carbon atoms, and mixture thereof; and 0.5 to 15 parts, by weight, of an acrylamide compound (IV) represented by the general formula of: CH.sub.2 .dbd.CHCONHCH.sub.2 OR; wherein R is an alkyl group having 1 to 10 carbon atoms. An aqueous emulsion adhesive is also provided which comprises the quarterly copolymer.
