ABSTRACT:
Vinyl acetate-ethylene copolymer latices having an inherent viscosity of not less than about 1.90 and demonstrating superior performance in the Time of Set Test and Vinyl Wetting Test are prepared by the process which comprises copolymerizing from about 60% to about 95% by weight of vinyl acetate monomer with from about 40% to about 5% by weight of ethylene monomer in an emulsified reaction medium containing:
