POLYMERIZABLE IMIDAZOLIDINONES AND POLYMERS THEREOF USEFUL AS NONWOVEN BINDERS Abstract Of The Disclosure Novel polymerizable imidazolidinone monomers, useful in the pre- paration of self-crosslinking polymers, have the general structure Image wherein R1 is H or a C1-C6 linear or branched alkyl or hydroxyalkyl group; X is a divalent radical selected from the group consisting of Image m being 0-5, and n being 1-5; R2 is H or CH3; R3 is H or Image with R' as defined above; and R4 and R5 are independently H or linear or branched C1-C4 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. ZnCl2) are used as formaldehyde-free binders for nonwoven textiles.
