    摘要: Ignition resistant carbonate polymers are made by incorporating a metal salt complex of polyether polyols into the polymer. The carbonate polymers are transparent with low haze and still have high ignition resistance. The ignition resistance can be improved by the addition aromatic compound.

    摘要: Carbonate polymer compositions exhibit good thermal stability and good non-yellowing characteristics. Compositions comprise a carbonate polymer (e.g., a homopolycarbonate of bisphenol A), a heat stabilizing phosphorous compound (e.g., an organo-phosphite or an organo-phosphonite), an epoxy compound containing internal acyclic ether linkages (e.g., a diglycidyl ether of a polypropylene glycol), and optionally a hindered phenol. Such compositions retain desirable properties upon exposure to hot and humid conditions.

    摘要: Flame retardant carbonate polymers containing an aromatic sulfimide, a monomeric or polymeric halogenated organic compound, a metal sulfate having a pka from 1 to 5 and a fibril forming polytetrafluoroethylene as additives in effective amounts give carbonate polymers that are not only flame retardant but are melt stable i.e. show little loss in molecular weight during processing or melt shearing.
