Abstract: A vinyl acetate-ethylene copolymer emulsion is disclosed, comprising a vinyl acetate-ethylene copolymer composed of from 10 to 40% by weight of an ethylene unit and from 90 to 60% by weight of a vinyl acetate unit and an emulsifying dispersant in an amount of from 2.5 parts by weight or more but less than 5.0 parts by weight per 100 parts by weight of the vinyl acetate unit, and having a mean particle size of not larger than 0.9 .mu.m and a solids content of from 65 to 75% by weight, wherein the emulsifying dispersant contains from 1.0 to 1.9 parts by weight of partially saponified polyvinyl alcohol prepared so as to have an average polymerization degree of from 300 to 1,000 and from 1.0 to 3.0 parts by weight of a polyoxyethylene nonionic surface active agent having an HLB of from 16.5 to 17.5 per 100 parts by weight of the vinyl acetate unit. A process for producing the vinyl acetate-ethylene copolymer is also disclosed.

Abstract: An improved cement composition having improved crack resistance, water resistance, and which comprises a mixture of a conventional cement composition with an ethylene-vinyl acetate copolymer emulsion containing 1 to 10 parts by weight of a polyvinyl alcohol and 0.1 to 10 parts by weight of a higher fatty acid ester of a polyvalent alcohol having an HLB of 10 or less per 100 parts by weight of the solid resin components of the emulsion.

Abstract: A process for producing an aqueous dispersion of vinyl acetate-ethylene copolymer containing an epoxide resin, which comprises emulsion-copolymerizing vinyl acetate, wherein an epoxide resin is dissolved, and ethylene at a pH value of 3 to 7 so that the ratio of vinyl acetate to ethylene is 60-95 : 40-5 by weight and the content of the epoxide resin is 0.5 to 60% by weight on the basis of the total weight of the solid resin components. The aqueous dispersion is useful as a two-pack type adhesive or coating composition in combination with a curing agent.
