ABSTRACT:
Novel polymerizable imidazolidinone monomers, useful in the preparation of self-crosslinking polymers, have the general structure ##STR1## wherein R.sup.1 is H or a C.sub.1 -C.sub.6 linear or branched alkyl or hydroxyalkyl group; X is a divalent radical selected from the group consisting of ##STR2## with R being H or CH.sub.3, m being 0-5, and n being 1-5; R.sup.2 is H or CH.sub.3 ; R.sup.3 is H or ##STR3## with R' as defined above; and R.sup.4 and R.sup.5 are independently H or linear or branched C.sub.1 -C.sub.4 alkyl groups. In a preferred embodiment, aqueous emulsions of the imidazolidinone-containing polymers (e.g. 45-60% vinyl acetate, 34-52% butyl acrylate, and 3-6% imidazolidinone) and an acid-curing catalyst (e.g. ZnCl.sub.2) are used as formaldehyde-free binders for nonwoven textiles.
