Blends of aromatic polycarbonates and epoxy-functional terpolymers

Abstract

Blends of A) 80 to 99 wt. % of high molecular weight, thermoplastic, aromatic polycarbonate with a molecular weight M.sub.w (weight average) of at least 10,000, which contains bifunctional carbonate structural units of the formula (I), ##STR1## in which R.sup.1 and R.sup.2 mutually independently mean hydrogen, halogen, C.sub.1 -C.sub.8 alkyl, C.sub.5 -C.sub.6 cycloalkyl, C.sub.6 -C.sub.10 aryl, preferably phenyl, and C.sub.7 -C.sub.12 aralkyl, m means an integer from 4 to 7, preferably 4 or 5, R.sup.3 and R.sup.4 individually selectably for each X, mutually independently mean hydrogen or C.sub.1 -C.sub.6 alkyl and X means carbon, providing that on at least one atom X, R.sup.3 and R.sup.4 simultaneously mean alkyl, B) 1 to 20 wt. % of a terpolymer prepared from 60 to 70 wt. % of ethylene, 37 to 20 wt. % of an acrylic acid ester of a C.sub.2 -C.sub.12 alcohol and 3 to 10 wt. % of a monomer with epoxy groups.
