Disclosed herein is a flame retardant composition comprising 20 to 80 weight percent of a polycarbonate; 1 to 20 weight percent of a halogenated phenoxyphosphazene flame retardant, where all weight percents are based on a total weight of the flame retardant composition. Disclosed herein too is a method comprising blending a 20 to 80 weight percent of a polycarbonate; and 1 to 20 weight percent of a halogenated phenoxyphosphazene flame retardant to produce a flame retardant composition, where all weight percents are based on a total weight of the flame retardant composition.

Flame retardant composition, methods of manufacture thereof and articles comprising the same

Disclosed herein is a flame retardant composition comprising a polycarbonate composition, glass fibers, and a flame retardant that comprises a phenoxyphosphazene compound. Disclosed herein too are methods for manufacturing a flame retardant composition that comprises blending a polycarbonate composition, glass fibers and a flame retardant that comprises a phenoxyphosphazene compound.

Flame retardant polycarbonate compositions, methods of manufacture thereof and articles comprising the same

A composition containing a polycarbonate, a polycarbonate-polysiloxane copolymer, an alicyclic hydrocarbon resin flow promoter, an inorganic filler, a flame retardant and an impact modifier. The compositions may include polycarbonate in an amount of 40% by weight or more of the combined weights of the polycarbonate, polycarbonate-polysiloxane copolymer, inorganic filler, flame retardant, flow promoter, and impact modifier compound wherein a molded sample of the thermoplastic composition is capable of achieving UL94 V0 rating at a thickness of 1.2 mm (&#xb1;10%); wherein the polymer composition has a melt viscosity of 185 Pa&#xb7;sec or less, when measured at 270&#xb0; C. and 1500 sec; and wherein a molded sample of the thermoplastic composition has a flexural modulus determined in accordance with ASTM D790 within 3800-8000 MPa; and wherein a 3.2-mm thick molded NII bar comprising the composition has a notched Izod impact strength of 40 to 200 J/m determined in accordance with ASTM D256 at 23&#xb0; C.
