Abstract
Provided are a flame-retardant polycarbonate resin composition capable of being formed into moldings having good impact resistance, high strength and good thermal stability that are intrinsic to polycarbonate resins and having good antistatic properties and good flame retardancy, and also injection moldings of the composition. The composition comprises 100 parts by weight of a resin or resin mixture of (A) from 50 to 100% by weight of a polycarbonate resin and (B) from 0 to 50% by weight of a styrenic resin, from 1 to 50 parts by weight of (C) a flame retardant, and from 0.1 to 5 parts by weight of (D) an anionic antistatic agent, and has a sodium sulfate content of at most 0.05% by weight. Optionally, the composition may contain (F) a fluoro-olefinic resin, (G) a rubber-like elastomer, and (H) an inorganic filler.
