摘要：
A copolymer emulsion for bonding nonwovens demonstrating increased blocking resistance comprising an aqueous medium having colloidally dispersed therein a copolymer consisting essentially of vinyl acetate, ethylene, a crosslinkable comonomer which is an N-acrylamidoglycolic acid or an acrylamidobutyraldehyde dialkyl acetal type compound, and a small amount of an acrylamide.
