Abstract: 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 water-dispersible copolymer salts.
