| abstract |
The application provides a terpolymer obtainable by copolymerization of (A) 1 to 70% by weight of at least one electron-deficient olefin, for example an anhydride of a monoethylenically unsaturated C 4 - to C 6 -dicarboxylic acid, (B) 1 to 85% by weight of at least one olefin which bears only hydrogen atoms and/or carbon atoms without electron-withdrawing substituents on the olefinic double bond thereof, for example of an isobutene homo‑ or copolymer with a number-average molecular weight of 100 to 500 000, and (C) 1 to 70% by weight of at least one alkoxyvinylsilane, and conversion products of this terpolymer obtainable by modification or crosslinking. |
