182-P-US03314 ABSTRACT A vinyl acetate-ethylene copolymer emulsion which is about 65-70% solids and has a viscosity of less than about 3,500 is disclosed. The emulsion is prepared by copolymerization of vinyl acetate and ethylene monomers in the presence of a stabllizing system consisting essentially of 2-4 wt%, based on vinyl acetate monomer, of a polyvinyl alcohol having a 100-600 degree of polymerization and 2-4 wt%, based on vinyl acetate monomer, of a surfactant. Such emulsions demonstrate an improved speed of set as an adhesive.
