A thermoplastic composition suitable for making articles having low gloss and good impact properties is disclosed. The composition contains The gloss of the composition is lower than that of a corresponding composition that contains none of component (C).

Thermoplastic molding composition based on AES rubber with low surface gloss

The present invention relates to flame-retardant polycarbonate compositions and methods for increasing the flame-retardancy of polycarbonate compositions. An &#x3b1;,&#x3c9;-alkoxy phenyl phenyloligosiloxane compound and an alkali metal sulfonate salt are added to the polycarbonate compositions. The addition of the &#x3b1;,&#x3c9;-alkoxy phenyl phenyloligosiloxane compound and the alkali metal sulfonate salt produces a polycarbonate composition having a flame-retardance rating of UL 94V-0 at 2 mm thickness or less.

Flame-retardant polycarbonate compositions

A thermoplastic molding composition that releases upon burning a limited amount of smoke is disclosed. The composition includes 95 to 60 percent aromatic (co)polycarbonate, 5 to 40 percent bromine-substituted oligocarbonate, and 0.04 to 0.2 percent alkali or alkaline-earth salt of perfluoroalkane sulfonic acid, the percents all occurrences being relative to the weight of the composition.

Flame resistant polycarbonate composition

A method of making a polyether-polydialkylsiloxane block copolymer is provided. The method comprises providing a mixture comprising at least one alkylene oxide and at least one silanol-terminated polydialkylsiloxane; and polymerizing the mixture in the presence of a double metal cyanide complex catalyst, and optionally in the presence of an aprotic solvent and/or an antioxidant. A polyether-polydialkylsiloxane block copolymer having a molecular weight of 150-50,000 g/mole and having a polydispersity index of 1.0 to 1.5 made by the above method is also provided.

Polyether-polysiloxane polyols

A flame-retardant thermoplastic molding composition is disclosed. The composition contains aromatic polycarbonate resin and sufficient amounts of poly(tetrafluoroethylene) and sulfo-modified polyester, that are effective to impart to the composition flame resistance that in accordance with UL-94 standard is rated V-0 at 1/16&#x2033; thick specimens.

Flame retardant, thermoplastic polycarbonate molding compositions

Thermoplastic polycarbonate compositions having high toughness

A thermoplastic molding composition comprising polycarbonate resin and additive, positive, amounts of stabilizer and salt is disclosed. The composition is characterized by its freedom from splay and by its improved flame retardance. The stabilizer of the invention is a physical mixture of poly(alkyl methacrylate) with fluorinated polyolefin, and the salt is an alkali metal or alkaline earth metal salt of perfluoroalkane sulfonic acid, aromatic sulfimide, or aromatic sulfonic acid.
