Abstract:
A process for the preparation of a solvent-resistant textile binder, comprising polymerizing by free-radical emulsion polymerization in the presence of emulsifier(s), and optionally drying the aqueous copolymer dispersion thereby obtained, wherein as monomers are employeda) one or more monomers selected from the group consisting of vinyl esters of unbranched or branched carboxylic acids having 1 to 12 C atoms, esters of acrylic acid or methacrylic acid with unbranched or branched alcohols having 1 to 12 C atoms, vinylaromatics, vinyl halides and alpha-olefins, andb) 0.01 to 10% by weight, based on the total weight of the copolymer, of one or more monomers b1) selected from the group consisting of the N-(C.sub.1-6 alkoxymethyl)acrylamides and N-(C.sub.1-6 alkoxymethyl)methacrylamides, or one or more monomers b2) selected from the group consisting of N-methylolacrylamide and N-methylolmethacrylamide, ormixtures of compounds b1) and compounds b2),wherein as emulsifier(s) are employedc) from 0.01 to 10% by weight, based on the overall weight of the copolymer, of one or more emulsifiers selected from the group consisting of the sulfosuccinic acid mono- and diesters, the ester groups of said sulfosuccinic acid mono- or diesters derived from C.sub.4-13 linear, branched, or cyclic aliphatic alcohols,said emulsifier c) being added during one or more of the stages prior to, during, or following polymerization of a) and b).
