Abstract
Abstract Thermoplastic molding compositions contain as essential components (A) from 1 to 90% by weight of a polycarbonate, (B) from 1 to 90% by weight of a polyester, (C) from 1 to 90% by weight of a polyamide, (D) from 0.5 to 30% by weight of a polymeric component having hydroxyl groups and in addition (E) from 0 to 30% by weight of an impact-modifying rubber and (F) from 0 to 60% by weight of a fibrous or particulate filler.

Claim 1
Independent Claim
147 words
A thermoplastic molding composition containing as essential components (A) from 1 to 90% by weight of a polycarbonate, (B) from 1 to 90% by weight of a polyester, (C) from 1 to 90% by weight of a polyamide, (D) from 0.5 to 30% by weight of a polymeric component having substantially freely accessible hydroxyl groups, which polymeric component is (1) a polycondensate of an aliphatic or aromatic diol or polyol with an epihalohydrin, (2) a polyolefin, polystyrene or rubber elastomer, each having freely accessible hydroxyl groups, (3) a polymer or copolymer containing a vinylphenylcarbinol, (4) a polymer or copolymer containing a vinylphenol, or (5) a phenol-formaldehyde polycondensate, which polymeric component is not identical to component (A), (B) or (C), and in addition (E) from 0 to 30% by weight of an impact-modifying rubber and (F) from 0 to 60% by weight of a fibrous or particulate filler.
Claim 2
Dependent Claim
