ABSTRACT:
This invention relates to a vinyl acetate-ethylene copolymer containing emulsion particularly adapted for the preparation of nonwoven goods. The vinyl acetate-ethylene emulsion is prepared by an improved process for producing an aqueous emulsion suitably adapted for producing non-woven goods said emulsion containing a vinyl acetate-ethylene copolymer wherein said copolymer contains from about 75-96% by weight of vinyl acetate. It is produced by forming an aqueous suspension of vinyl acetate, ethylene, and stabilizer, initiating the polymerization of the reaction mixture by the addition of catalysts, and adding from about 0.5-10% by weight of the vinyl acetate of a crosslinkable monomer. The improvement for enhancing the absorptivity of the copolymer comprises:
