  • Patent number: 11859047
    Abstract: Provided is a polycarbonate resin composition and a molded product comprising same. The polycarbonate resin composition comprises a linear polycarbonate resin, a branched polycarbonate resin, a fluorinated sulfonate-based metal salt, a phenyl methyl silicone oil, and a phenyl methyl silicone resin. The linear polycarbonate resin and branched polycarbonate resin include a repeating unit of the following Chemical Formula 1: wherein in Chemical Formula 1: R1 to R4 are each independently hydrogen, C1-10 alkyl, C1-10 alkoxy, or halogen; and Z is C1-10 alkylene unsubstituted or substituted with phenyl, C3-15 cycloalkylene unsubstituted or substituted with C1-10 alkyl, O, S, SO, SO2, or CO.
