Title:
ポリカーボネート成形組成物
Document Type and Number:
Japanese Patent JP2010523742
Kind Code:
A
Abstract:
The invention relates to talcum-reinforced polycarbonate compositions comprising: A) a polycarbonate, polyester carbonate or a mixture thereof, B) optionally, at least one polymer selected from one of the group consisting of graft polymer produced in an emulsion polymerisation process, graft polymer produced in a bulk polymerisation process, rubber-free vinyl homopolymer and rubber-free vinyl copolymer, C) talcum, D) a Brönstedt acid, and optionally E) at least one polymer additive, and wherein the composition is free of aromatic or partially aromatic polyesters. Compared to the known prior art the inventive compositions have an improved ductility, thermal resistance towards deformation and thermal stability during compounding and processing (molding). The invention also provides for the use of the composition for the production of molded articles and two-component structural parts.
