  • Publication number: 20130253109
    Abstract: In a polycarbonate resin composition containing a polycarbonate resin and a polycarbosilane compound, the use of the polycarbosilane compound modifies the surface properties of the polycarbonate resin composition without adversely affecting the intrinsic characteristics of the polycarbonate resin, such as transparency, heat resistance, and mechanical properties, e.g., impact resistance. A polycarbonate resin composition containing 100 parts by mass of a polycarbonate resin, 0.001 to 1 part by mass of a metal salt compound, and 0.005 to 5 parts by mass of a polycarbosilane compound has significantly improved flame resistance and high transparency and causes markedly reduced outgassing and mold fouling, without losing impact resistance and heat resistance.
