    摘要: The present invention relates to flame resistance additives for organic polymers, and in particular polyphosphonate-type flame resistance additives in a polycarbonate or a polyester carbonate and/or in blends of polycarbonate or a polyester carbonate with an acrylonitrile, butadiene, and styrene terpolymer. The aromatic polyphosphonate compounds of the present invention are represented by the structure, wherein a and b are each from 0 to 6, with a+b being from 2 to 6, each R is independently hydrogen, unsubstituted or inertly substituted alkyl having up to 6 carbon atoms, —NO2, —NR12, —C≡N, —OR1, —C(O)OR1, or —C(O)NR12 (wherein R1 is hydrocarbyl or hydrogen), each R2 is independently hydrogen, alkyl or inertly substituted alkyl, each R3 is a covalent bond or a divalent linking group, and each R4 is independently an alkyl, aryl, inertly substituted alkyl or inertly substituted aryl group.
