A vinyl acetate-ethylene copolymer emulsion having a solids content of at least about 65 percent by weight comprises about 5 to 40 percent by weight ethylene; about 60 to 95 percent by weight vinyl acetate; greater than about 3.0 percent by weight of a polyvinyl alcohol having a degree of polymerization of from about 100 to 500; about 1 to about 4 percent by weight of an ethyoxylated aliphatic surfactant having an HLB of from about 16.5 to 18.0; and about 0.2 to about 1.0 weight percent of a dispersant.

High solids vinyl acetate-ethylene emulsions

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.
