Abstract

A textile binder in the form an aqueous copolymer dispersion or of a copolymer powder obtainable by means of free-radical emulsion polymerization of PA1 a) one or more monomers from the group consisting of vinyl esters, esters of acrylic acid and methacrylic acid, vinylaromatics, vinyl halides and alpha-olefins and PA1 b) from 0.01 to 10% by weight, based on the overall weight of the copolymer, of one or more monomers b1) from the group consisting of the N-(alkoxymethyl)acrylamides and N-(alkoxymethyl)-methacrylamides or one or more monomers b2) from the group consisting of N-methylolacrylamide and N-methylolmethacrylamide, or mixtures b1) and b2), where as emulsifier(s) PA2 from 0.01 to 10% by weight, based on the overall weight of the copolymer, of one or more emulsifiers from the group of the monoesters or diesters of sulfosuccinic acid with linear, unbranched or branched, or cycloaliphatic alcohols, are employed or are added to the aqueous copolymer dispersion after the end of the emulsion polymerization.
