Abstract
Formaldehyde-free heat resistant binders for flexible nonwoven products may be prepared using an emulsion polymer comprising 100 parts by weight of C.sub.1 -C.sub.4 alkyl acrylate or methacrylate or styrene/acrylate ester monomers, 0.5 to 5 parts of a hydroxyalkyl acrylate or methacrylate, 3 to 6 parts of methyl acrylamido glycolate methyl ether and 0.1 to 5 parts of a multifunctional comonomer. The binders are useful in the formation of heat resistant flexible products for use in roofing, flooring and filtering materials.
