Copolymers I bearing functional groups and consisting of a) 30 to 70 mol% of at least one monoethylenically unsaturated C4 to C12 dicarboxylic acid or its anhydride and b) 30 to 70 mol% of an oligomer of a 1-olefine with 3 to 14 C atoms, in the form of up to at least 85 % of an isomer with a vinyl group of the formula -CH=CH2 in the end position and a mean molecular weight of 300 to 10,000. Reaction products of copolymer I with NH, OH or SH-functional compounds are suitable as dispersing agents for washing and cleaning agent formulations, water-repelling agents for leather and pelts, flow improvers and paraffin dispersants for crude oils and refined mineral oils and lubricant and fuel additives. |
