ABSTRACT:
Copolymers based on ethylenically unsaturated dicarboxylic anhydrides, long-chain olefins and fluoroolefins Copolymers containing 10 to 60% by weight of bivalent structural units of the formula A ##STR1## wherein R.sup.1 and R.sup.2, independently of one another, are hydrogen or C.sub.1 -C.sub.6 -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--HR.sup.3,
where R.sup.3 is C.sub.1 -C.sub.40 -alkyl, C.sub.3 -C.sub.40 -alkenyl, C.sub.5 -C.sub.20 -cycloalkyl or C.sub.6 -C.sub.18 -aryl, the group --N--(R.sup.3).sub.2,
where R.sup.3 are identical or different and have the abovementioned meaning, and/or the group --O--R.sup.4,
where R.sup.4 is hydrogen, an alkali metal cation, one equivalent of an alkaline earth metal ion, a cation of the formula H.sub.2 N.sup..sym. (R.sup.3).sub.2 or H.sub.3 N.sup..sym. R.sup.3, C.sub.1 -C.sub.40 -alkyl, C.sub.5 -C.sub.20 -cycloalkyl or C.sub.6 -C.sub.18 -aryl, 30 to 89% by weight of bivalent structural units of the formula B ##STR2## wherein R.sup.5 is hydrogen or C.sub.1 -C.sub.4 -alkyl and
R.sub.6 is C.sub.6 -C.sub.40 -alkyl or C.sub.6 -C.sub.18 -aryl, and
1 to 20% by weight of bivalent structural units of the formula C ##STR3## wherein n is a number from 6 to 24.
The invention also relates to a process for the preparation of these copolymers and to the utilization thereof.
