Copoltmers based on ethylenically unsaturated dicarbox- ylic anhydrides, long-chain olefins and fluoroolefins Copolymers containing 10 to 60% by weight of bivalent structural units of the formula A Image (A) wherein R1 and R2, independently of one another, are hydrogen or C1-C6-alkyl, a and b are zero or one and a + b is one, X and Y are identical or different and are the group -N-HR3, where R3 is C1-C40-alkyl, C3-C40-alkenyl, C5-C20-cyclo- alkyl or C6-C18-aryl, the group -N-(R3)2, where R3 are identical or different and have the above- mentioned meaning, and/or the group -O-R4, where R4 is hydrogen, an alkali metal cation, one equi- valent of an alkaline earth metal ion, a cation of the formula H2N?(R3)2 or H3N?R3, C1-C40-alkyl, C5-C20-cycloalkyl or C6-C18-aryl, 30 to 89% by weight of bivalent structural units of the formula B Image (B) wherein R5 is hydrogen or C1-C4-alkyl and R6 is C6-C40-alkyl or C6-C18-aryl, and 1 to 20% by weight of bivalent structural units of the formula C Image (C) wherein n is a number from 6 to 24. The invention also relates to a process for the prep- aration of these copolymers and to the utilization thereof.
