Abstract
Low viscosity, fast curing binders for nonwoven cellulosic materials comprise an aqueous dispersion of discrete particles of a highly functionalized emulsion copolymer resulting from the copolymerization of a water insoluble olefinic non-ionic organic compound, a water soluble olefinic carboxylate compound and a water soluble olefinic hydroxy ester or a water soluble olefinic amide or a mixture of hydroxy ester and amide. The emulsion copolymer dispersion is admixed with a latex to provide a binder having a relatively low viscosity and capable of reaching about 80 percent of fully cured wet tensile strength in 8 seconds or less.
