ABSTRACT:
A fire-retardant polycarbonate resin composition comprising 100 parts by weight of a halogen atom-free conventional polycarbonate resin having a viscosity-average molecular weight of 10,000 to 30,000, a fire retardant in an amount necessary for imparting fire retardance, and 5 to 60 parts by weight of a halogen atom-free ultrahigh-molecular-weight polycarbonate resin having a viscosity-average molecular weight of 100,000 to 250,000, said composition showing a flow value of 0.01 to 0.3 cm.sup.3 /sec when measured at 280.degree. C. under a load of 180 kg/cm.sup.2 using a die having a hold diameter of 1 mm and a length of 10 mm and performance rated at class V-0 when conducting a burning test in accordance with a UL-94 test about a test piece having a thickness of 1 mm.
