ABSTRACT:
Emulsion binders which do not generate formaldehyde during cure are prepared for use in nonwoven products by using a emulsion copolymer comprising by weight about 100 parts C.sub.1 -C.sub.8 alkyl acrylate or C.sub.1 -C.sub.8 alkyl acrylates in combination with styrene, acrylonitrile, vinyl acetate and combinations thereof, about 1 to 20 parts hydroxyalkyl acrylate or methacrylate, about 2 to 20 parts meta or para isopropenyl-.alpha.,.alpha.-dimenthyl benyl isocyanate and optionally 0.1 to 5 parts of a multifunctional monomer. The binders are useful in the formation of heat resistant flexible products for use in roofing, flooring and filtering materials, as well as for facings and other applications in general purpose nonwoven products.
