Trihalophenoxy terminated polycarbonate resin composition containing salt of organic sulfonic acid

摘要

A polycarbonate resin composition comprisingPP (a) 100 parts by weight of a polycarbonate comprisingPP(1) a repeating unit (I) represented by the following formula: ##STR1## and a repeating unit (II) represented by the following formula: ##STR2## wherein X.sup.1 to X.sup.4 are each a halogen atom and (2) a trihalogenophenoxy group as the end group thereof, the polycarbonate having viscosity average molecular weight of 10,000 to 50,000, and 1 to 10 mol % of the repeating unit (I) in the main chain andPP (b) 0.01 to 0.2 part by weight of an alkali metal salt or an alkaline earth metal salt of an organosulfonic acid. The polycarbonate composition is excellent in all of flame retardance, impact resistance, and a thermostability at molding. Accordingly, the polycarbonate resin composition is extensively and effectively used industrially in home electric appliances, office automation devices, construction materials and the like.
