    Abstract: A process for the preparation of aqueous (meth)acrylate copolymer dispersions by polymerising the monomers in two steps of different monomer composition and additionally using crosslinking monomers in aqueous emulsion at a conventional temperature in the presence of conventional emulsifiers and polymerisation initiators, wherein from 40 to 99.5 % by weight of the entire amount of monomers are polymerised in the first step and from 60 to 0.5 % by weight are polymerised in the second step, from 0.5 to 10 % by weight, based on the total amount of monomers, of (meth)acrylamidoglycolic acid and/or the methyl ester and/or methyl ether thereof are polymerised in the second step and from 0 to 1.8 % by weight, based on the total amount of monomers, of the amidoglycolic acid compounds are polymerised in the first step. The copolymer dispersions obtained are used as binders for sheet-like textile structures made from fibres.

    Abstract: Aqueous dispersions of synthetic resins are obtainable by combining an aqueous starting dispersion of a polymer A which has a glass transition temperature of from -50 to +60 DEG C and is built up from monoethylenically unsaturated monomers which carry, apart from carboxyl groups and derivatives thereof, no further polymerisable or mutually condensable groups, and optionally butadiene, and an aqueous solution of a polymer B which is built up essentially from N-hydroxycarboxymethylamides of acrylic and/or methacrylic acid and/or from water-soluble salts of these N-hydroxycarboxymethylamides, at the beginning, during and/or after completion of the preparation of the aqueous starting dispersion, with the proviso that the solid content of the polymer B, based on the total amount of polymers A and B, is from 0.5 to 10% by weight.
