摘要：
Flame retardant blends comprising a polycarbonate portion containing spirobiindane units, at least one addition polymer such as a styrene-acrylonitrile or ABS copolymer, and at least one phosphoryl flame retardant have high temperature stability properties superior to those of similar blends not containing the spirobiindane units. Blends in which the polycarbonate portion contains such units in amounts up to 5 mole percent also have excellent ductility.
