Abstract: Method of controlling the mobility of aqueous flows through fissures, slits or pores, in particular of flooding waters in tertiary production of crude oil, wherein cationic surfactants which, on measurement of the electric birefringence with a pulsed rectangular electrical field in pure aqueous solutions, give a measurement signal, from the decrease of which a relaxation time of 0.01 mu s to 10 ms, in particular of 0.1 mu s to 2 ms, results, are added to the aqueous medium. Preferred suitable cationic compounds are those of the general formula R1-K+A- in which R1 denotes C12-C26-alkyl or C12-C26-alkenyl, K+ denotes a group of the formula R2 denotes C1-C3-alkyl, preferably methyl, R'2 denotes C1-C3-alkyl, preferably methyl, R''2 denotes C1-C3-alkyl, preferably methyl, or R''2 denotes (CH2CH2O)xH, where x denotes from 1 to 3, preferably 1 to 2, and A- denotes an anion of the following formulae: SCN31, R3SO3-, where R3 is C6-C9-alkyl or -alkenyl and the sum of the carbon atoms in R1 and R3 should be at least 21; +TR where Hal is chlorine or bromine, R4 is C1-C5-alkyl, C2-C5-alkenyl or C1-C5-alkoxy in positions 3, 4, 5 and 6 and R5 is hydrogen or hydroxyl in positions 2 and 3 relative to the carboxyl group, or where R6 is COO- or SO3- and R7 is hydrogen or methyl.

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.
