The present invention provides resin compositions comprising a thermoplastic resin, at least one phosphoramide having a glass transition point of at least about 0&deg; C., preferably of at least about 10&deg; C., and most preferably of at least about 20&deg; C.; and at least one adjunct flame retardant. The present invention also relates to articles made from the resin compositions. The present invention also provides methods to make the resin compositions having improved heat properties over compositions known in the art.

Flame retardant resin compositions containing phosphoramides and method for making

The present invention provides resin compositions comprising a thermoplastic resin and at least one phosphoramide having a glass transition point of at least about 0&deg; C., preferably of at least about 10&deg; C., and most preferably of at least about 20&deg; C., of the formula:

Flame retardant resin compositions containing phosphoramides, and method for making

Flame retardant blends comprising at least one polyestercarbonate, 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 containing polycarbonate in place of polyestercarbonate.

Flame retardant polymer blends, and method for making

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.

A thermoplastic resin composition contains an aromatic carbonate resin, a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, wherein the rubber phase of the copolymer is made by an aqueous emulsion polymerization in the presence of a (C.sub.30 -C.sub.108)polyacid surfactant, and a flame retarding amount of an organophosphorus flame retardant.

Flame retardant polycarbonate resin/ABS graft copolymer blends having
