Abstract

Thermoplastically processable polymer mixtures with high solvent resistance. The polymer mixtures are made up of PA1 A) 2-98 wt. % of a polymer that is composed of at least 80 wt. % of monomer units of CH.sub.2 .dbd.CF.sub.2, and PA1 B) 98-2 wt. % of a polymer that consists of (.alpha.) 20-90 wt. % of monomer units of Formula I ##STR1## in which R stands for an alkyl group with 1 to 3 carbon atoms and X stands for a ##STR2## and of (.beta.) 80-10 wt. % of a chemically crosslinked polymer with a glass transition temperature below 0.degree. C., that is bonded to at least 5 wt. % of the polymer formed from the monomer of Formula (I).
