Abstract
Vinyl C.sub.1 to C.sub.3 alkanoate/C.sub.2 to C.sub.4 alkylene copolymer emulsions e.g. vinyl acetate/ethylene, are usable as wet adhesives and pressure sensitive adhesives for a number of applications. Their bonding to the surfaces of lower polarity, e.g. polyethylene, is improved by including vinyl esters of C.sub.4 to C.sub.18 primary carboxylic acids as a monomer.
