Abstract

The application provides a terpolymer obtainable by copolymerizing (A) 1% to 70% by weight of at least one electron-deficient olefin, an example being an anhydride of a monoethylenically unsaturated C4 to C6 dicarboxylic acid, (B) 1% to 85% by weight of at least one olefin which on its olefinic double bond carries only hydrogen atoms and/or carbon atoms without electron-withdrawing substituents, an example being an isobutene homopolymer or copolymer having a number-average molecular weight of 100 to 500 000, and (C) 1% to 70% by weight of at least one alkoxyvinylsilane, and also derivatives of this terpolymer that are obtainable by modification or crosslinking.
