Abstract (en)

[origin: US4476182A] What are disclosed are a method for the reinforcement of a fibrous article with an aqueous dispersion of a resin, free of formaldehyde and acrylonitrile, comprising at least 40 weight percent of alkyl acrylates and/or methacrylates having at least 4 carbon atoms in the alkyl group; up to 57 weight percent of alkyl acrylates or methacrylates having not more than 3 carbon atoms in the alkyl group, or of styrene; less than 1 weight percent of acrylic acid or of methacrylic acid; and from 3 to 15 weight percent of a hydroxyalkyl ester of an unsaturated carboxylic acid, as well as reinforced fibrous articles made by this method and distinguished by high wet strength and by low loss of the resin binder on washing with boiling water.
