ABSTRACT:
Vinyl acetate/ethylene (VAE) copolymer emulsions having extended shelf life which are particularly suited for use as binders of nonwoven substrates. The copolymer emulsions are prepared by incorporating 1 to 45 wt % tetramethylol glycoluril, based on the amount of vinyl acetate in the copolymer, into an aqueous dispersion of a copolymer consisting essentially of 60 to 94 wt % vinyl acetate, 5 to 30 wt % ethylene and 1 to 10 wt % of a crosslinkable comonomer. Suitable crosslinking monomers include N-acrylamidoglycolic acid and N-methylol acrylamide. Nonwoven products formed by depositing the emulsion onto a nonwoven substrate exhibit significantly improved resistance to organic solvents.
