    • A polycarbonate resin composition having excellent flame retardancy and/or low-temperature impact resistance. The composition having excellent flame retardancy comprises 1-100 parts by weight of a polycarbonate resin and/or a copolyester carbonate having an aliphatic segment and 99-0 parts by weight of an SAN resin and further contains 0.5-40 parts by weight of each of two rubber components, i.e., an ABS resin and a composite rubbery graft copolymer prepared by grafting a vinylic monomer onto a composite rubber composed of polyorganosiloxane and polyalky (meth)acrylate and 1-30 parts by weight of a phosphoric ester compound as a flame retardant. This composition has such an excellent flame retardancy that a thin-wall molding thereof can pass the V or 5V test of UL94. The composition having excellent low-temperature impact resistance comprises 1-99 parts by weight of a polycarbonate resin and/or a copolyester carbonate having an aliphatic segment and 99-1 parts by weight of an SAN resin and further contains 0.5-40 parts by weight of each of the abovementioned two rubber components. The impact resistance is especially remarkable at low temperatures.
    • 具有优异的阻燃性和/或耐低温冲击性的聚碳酸酯树脂组合物。 具有优异阻燃性的组合物包含1-100重量份的聚碳酸酯树脂和/或具有脂肪族链段的共聚酯碳酸酯和99-0重量份的SAN树脂,并且还含有0.5-40重量份的 两种橡胶组分,即ABS树脂和通过将乙烯基单体接枝到由聚有机硅氧烷和聚亚烷基(甲基)丙烯酸酯组成的复合橡胶上制备的复合橡胶接枝共聚物和1-30重量份作为阻燃剂的磷酸酯化合物 。 该组合物具有这样的优异的阻燃性,使得其薄壁成型可以通过UL94的V或5V测试。 具有优异的耐低温冲击性的组合物包含1-99重量份的聚碳酸酯树脂和/或具有脂肪族链段的共聚酯碳酸酯和99-1重量份的SAN树脂,并且还含有0.5-40重量份 的上述两种橡胶组分。 耐冲击性在低温下特别显着。
