Copolymers based on olefinic unsaturated radical ring-opening ketene derivatives

摘要

The invention relates to copolymers built up from A) from 99.5 to 75 % of olefinically unsaturated monomers containing hetero atoms, B) from 0.5 to 25 % of unsaturated compounds of the formula I IMAGE and C) from 0 to 20 % of further olefinically unsaturated monomers where X is O, S or NR1 and R is optionally substituted C2-C6-alkylene, and R1 is C1- to C8-alkyl or phenyl. The products according to the invention are suitable as coating and impregnation compositions and in particular as contact adhesives.
