Abstract
A vinyl acetate-ethylene copolymer emulsion having a solids content of at least 65 percent by weight is disclosed. Specifically, the copolymer emulsion comprises about 5 to 40 percent by weight ethylene, about 60 to 95 percent by weight vinyl acetate, about 0.8 to 2.0 percent by weight of a fully or partially hydrolyzed polyvinyl alcohol, and a mixture of nonionic ethoxylated alkyl phenol surfactants having a HLB of from about 16.0 to 16.5.
