Abstract: A thermoplastic composition comprises 55 to 97 weight percent of a polycarbonate; 1 to 25 weight percent of a polysiloxane-polycarbonate comprising siloxane units of the formula: wherein each occurrence of R is the same or different, and is a C1-30 monovalent organic group, wherein E is 1 to 1,000, and wherein the polysiloxane-polycarbonate comprises 0.1 weight percent to 50 weight percent siloxane units; 1 to 10 weight percent of an impact modifier; and 1 to 10 weight percent of a filler, wherein the filler has a particle size with D50 less than 2.7 micrometers. The thermoplastic composition has good flame retardance, flexural modulus, impact and surface appearance. A method of making and articles prepared from the thermoplastic composition are also disclosed.

Abstract: A flame retardant resin composition possessing high anti-thermal characteristic, excellent anti-impact characteristic and moreover, high degree of flame retardation characteristic, comprising: a polycarbonate resin (A-1), optionally a thermoplastic resin (A-2) other than polycarbonate group resin, a phosphoric ester (B); and an alkoxy group-containing organopolysiloxane (C) expressed by the average compositional formula R1aSi(OR2)bO(4-a-b)/2, where R1 is a substituted or unsubstituted univalent hydrocarbon group containing an aryl group as an essential component; R2 is a substituted or unsubstituted univalent hydrocarbon group; R1 and R2 may be the same as or different from each other; 0.2?a?2.7; 0.2?b?2.4; and a+b<3.
