Abstract
A formaldehyde-free latent crosslinking monomer represented by the formula ##STR1## in which R.sup.1 and R.sup.2 are C.sub.1 -C.sub.3 alkyl; R.sup.3 is hydrogen, C.sub.1 -C.sub.3 alkyl, or R.sup.4 --C(O)--; and R.sup.4 is C.sub.1 -C.sub.3 alkyl or C.sub.6 -C.sub.8 aryl, contains an allyl group capable of undergoing addition copolymerization and a dialkoxy ethyl group capable of crosslinking under acidic conditions. The monomer can be copolymerized with comonomers to form emulsion polymers for use as formaldehyde-free binders in nonwoven textiles. Methods for the preparation of the monomer, the polymers, and the nonwoven fabrics are described.
