  • Flame retardant compositions, articles comprising the same and methods of manufacture thereof
    Patent number: 9023922
    Abstract: Disclosed herein is a flame retardant composition comprising a polycarbonate; a polylactide; and a flame retardant; where the flame retardant is a phenoxyphosphazene, a di- or polyfunctional aromatic phosphorus-containing compound, or a combination comprising at least one of the foregoing flame retardants. Disclosed herein is a method comprising blending a polycarbonate, a polylactide and a flame retardant to form a flame retardant composition; where the flame retardant is a phenoxyphosphazene, a di- or polyfunctional aromatic phosphorus-containing compound, or a combination comprising at least one of the foregoing flame retardants.

  • Flame retardant polycarbonate compositions, methods of manufacture thereof and articles comprising the same
    Patent number: 9018286
    Abstract: Disclosed herein is a flame retardant composition comprising 20 to 80 weight percent of a polycarbonate composition; where the polycarbonate composition comprises a polysiloxane-carbonate copolymer; an impact modifier in an amount of 0.5 to 25 weight percent; and 1 to 20 weight percent of a phosphazene compound; where all weight percents are based on the total weight of the flame retardant composition. Disclosed herein too is a method comprising blending 20 to 80 weight percent of a polycarbonate composition; where the polycarbonate composition comprises a polysiloxane-carbonate copolymer; an impact modifier in an amount of 0.5 to 25 weight percent; and 1 to 20 weight percent of a phosphazene compound to produce a flame retardant composition; where all weight percents are based on the total weight of the flame retardant composition; and extruding and molding the flame retardant composition.
