Polycarbonate resin composition

Abstract

Abstract PURPOSE:To obtain the titled composition of improved thermal stability when melted, outstanding in moldability, heat and impact resistances, etc., suitable for electric parts, etc., by incorporating polycarbonate with specified amount of specific potassium titanate fiber. CONSTITUTION:The objective composition can be obtained by incorporating (A) 80-95wt% of a polycarbonate derived from condensation between a dihydric phenol of formula I (X is 1-10C alkylene, etc.; R<1> and R<2> are each halogen, etc.; m and n are each 0-4; P is 0 or 1) and a carbonic acid derivative with (B) 20-5wt% of potassium titanate fiber basically of formula II in a needle-like crystalline form with an average fiber length 5-150mum, average fiber diameter 0.05-2mum and free potassium content <=0.25wt% (pref. <=0.1wt%).
