摘要

The present invention relates to salts of copolymers of ethylenically unsaturated carboxylic acids and ethylenically unsaturated fatty acid derivatives containing (A) 1-99% by weight of structural units A of the formula IMAGE where R1 is hydrogen or C1-C4-alkyl, R2 is hydrogen or C1-C4-alkyl, R3 is hydrogen or C1-C4-alkyl, preferably methyl, X is -(CH2)0-10- or C6-C18-aryl, preferably phenyl and M is an alkali metal, alkaline earth metal or ammonium ion, (B) 99-1% by weight of structural units B of the formula IMAGE where R4 is C2-C16-alkyl or C2-C16-alkenyl, Y is C1-C13-alkylene, -CH2-(CH=CH-CH2)1-5- or -(CH=CH)1-3- and Z is a group of the formula CN, C(O)N(R5)2, where R5 is hydrogen, C1-C18-alkyl, C1-C18-alkenyl and/or -(CH2)1-3-OH, COOR6, where R6 is C1-C36-alkyl, preferably C1-C5-alkyl or C16-C36-alkyl, IMAGE (C) 0-40% by weight of structural units C of the formula IMAGE where R1, R2 and R3 are as defined above and W is a group of the formula CN, C(O)N(R5)2, where R5 is as defined above, COOR7, where R7 is C1-C18-alkyl, preferably C1-C10-alkyl and (D) 0-40% by weight of structural units D of the formula IMAGE where V is C6-C18-aryl, preferably phenyl or phenoxyacetyl, C4-C6-lactam, preferably N-pyrrolidyl, a group of the formula O-R7, where R7 is C1-C18-alkyl, preferably C1-C10-alkyl, a group of the formula (O)C-R7 or a group of the formula OOC-R7. The present invention also provides a process for the preparation thereof and the use thereof.
