  • Patent number: 9085674
    Abstract: A polycarbonate resin composition includes a polycarbonate resin; an inorganic filler, wherein the inorganic filler includes talc; and a novel silane compound represented by Formula 1: wherein R1 is C6 to C30 alkyl, R2 is a C6 to C30 hydrocarbon group, R3 is hydrogen or C1 to C5 alkyl, and n has an average value from about 0.1 to about 3. The polycarbonate resin composition can have excellent impact resistance with minimal or no reduction in molecular weight of the polycarbonate resin.
