Salts of copolymers of ethylene or unsaturated carboxylic acids and ethylenically unsaturated fatty acid derivatives are described. (A) 1-99 weight-it of structural units k of the formula. where. R represents hydrogen or C 1 -C 4 alkyl ,. R represents hydrogen or C 1 -C 4 alkyl ,. R represents hydrogen or C 1 -C 4 alkyl, preferably methyl. X represents - (CH) - or C 1 -C 6 aryl, preferably phenyl and. M means an alkali, alkaline earth or ammonium ion. (B) 99-1% by weight of structural units B of the formula. where '. means C 1 -C 4 alkyl or C 1) -lkenyl ,. Y represents C - alkylene, -CH- (CH-CH) - or. - (CH-CH) ^ - and. Z can have several meanings and i.a. means a group of the formula CN, C (O) N (R), where R. i.a. may represent hydrogen or C 1 -C 6 alkyl. (C) 0-40% by weight of structural units C of the formula. where, and has the meaning given above and. W represents a group of the formula C (D) 0-40 weight percent structural units D of the formula. wherein V represents CC-aryl, preferably phenyl or phenoxyacetyl, CC-lactam, preferably N-pyrrolidyl, a group of the formula OR, wherein R represents C-C8-alkyl, preferably CC-alkyl, a group of the formula (O) C-R a group of the formula 00C-R.
