Patent ID: 8779033

Claim:
A composition comprising A) 10 to 85 parts by weight of a polycarbonate, and/or a polyester carbonate, B) 10 to 50 parts by weight of a rubber-free vinyl copolymer of B.1 70 to 80 wt. %, based on the total weight of component B, of styrene and B.2 20 to 30 wt. %, based on the total weight of component B, of acrylonitrile C) 9.94 to 50 parts by weight of sized glass fiber with C.1 a glass fibers comprising at least one component selected from the group consisting of continuous strands, long glass fiber and chopped glass strands, C.2 a size, and C.3 optionally an adhesion promoter, wherein the size C.2 consists essentially of C.2.1 50 to 100 wt. %, based on the total weight of C.2, of an epoxy polymer comprising an epoxy resin made from, C.2.1.1 epichlorohydrin and C.2.1.2 bisphenol A as bisfunctional alcohol, and C.2.2 0 to 50 wt. %, based on the total weight of C.2, of at least one polymer selected from the group consisting of the polyurethanes, polyolefins, acrylate-containing polymers, styrene-containing polymers and polyamides, and wherein the sized glass fiber has a carbon content of 0.1 to 1 wt. %, D) 0 to 2 parts by weight of a rubber-modified graft polymer which is substantially free from double bonds and is selected from the group consisting of acrylate rubber, silicone rubber and silicone-acrylate composite rubber, and E) 0 to 10 parts by weight of a polymer additive, the composition being free from rubber-modified polymers which differ from component D), wherein the composition has a stress cracking ESC resistance in rapseed oil at room temperature of at least 8 to 21 hours as measured under ISO 4599.
