    Abstract: Copolymers prepared by emulsion or solution copolymerization, initiated by free radicals, of unsaturated copolymerizable monomers, the copolymers being built up from (a) 1-45% by weight of ethylenically unsaturated carboxylic acids, (b) 0.5-30% by weight of a surface-active crotonic acid ester, (c) 30-85% by weight of methacrylic acid esters or acrylic acid esters of aliphatic (C1-C18)-alcohols, (d) 0-40% by weight of other ethylenically unsaturated comonomers, (e) 0-3% by weight of polyethylenically unsaturated compounds and (f) 0-5% by weight of molecular weight regulators, and, if appropriate, the free acid groups of the copolymers subsequently having been partly or completely neutralized by addition of bases and converted into water-soluble or colloidally water-dispersible copolymer salts. In addition, processes for the preparation of the copolymers by solution or emulsion copolymerization and, if appropriate, subsequent conversion thereof into the copolymer salts, and the use of the products as viscosity-increasing and rheology-modifying substances in aqueous systems, in particular aqueous dispersions, preferably for thickening emulsion paints, emulsion gloss lacquers, textile printing pastes and paper printing pastes, and furthermore as sizing agents in the textile industry.

    Abstract: of the disclosure: Aqueous functional fluids, in particular hydraulic and metal-working fluids, containing a copolymer which is prepared by emulsion or solution copolymerization, initiated by free radicals, of unsaturated, copolymerizable monomers, the copolymers being built up from: a) 1 - 60% by weight of ethylenically unsaturated carboxylic acids, b) 0.5 - 30% by weight of a surface-active unsaturated ester, c) 30 - 85% by weight of methacrylic acid esters or acrylic acid esters of aliphatic (C1-C18)-alcohols, d) 0 - 40% by weight of other ethylenically unsaturated comonomers, e) 0 - 3% by weight of polyethylenically unsaturated compounds, and f) 0 - 5% by weight of molecular weight regulators, and, if appropriate, the free acid groups of the copolymers subsequently having been partly or completely neutralized by addition of bases, and converted into water-soluble or colloidally waterdispersible copolymer salts.
