Abstract
There is provided an antistatic polycarbonate resin composition and molded product formed by melt-molding the said resin composition, which resin composition has totally well balanced excellent properties including heat resistance, in which yellow- or brown-coloring can be prevented even though under melt-kneading step, molding step and such a circumstance that it is used at high temperature for long times, and the fluidity is improved without notably deterioration of mechanical strengths and transparency. A polycarbonate resin composition comprising 100 parts by weight of polycarbonate resin, 0.1 to 5.0 parts by weight of phosphonium sulfonate (A) represented by the following chemical formula (1), 0.1 to 10 parts by weight of aromatic polycarbonate resin oligomer (B) and 0.01 to 8 parts by weight of caprolactone-based polymer (C); and a molded product produced by melt-molding the said polycarbonate resin.
