Polycarbonate compositions with high flame retardance are disclosed. The compositions include a polycarbonate having repeating units derived from a monomer with an ester side group, and also include a flame retardant additive. These compositions may be further blended with another polycarbonate. The resulting compositions have high flame retardance and improved anti-drip properties.

Polycarbonate compositions with improved flame retardance

Provided herein are polycarbonate blend compositions, methods for making polycarbonate blend compositions and articles containing the polycarbonate blend composition, wherein the polycarbonate blend composition comprises a first polycarbonate and a second polycarbonate wherein the polycarbonate blend has a glass transition temperature (Tg) between 148&#xb0; C. and 155&#xb0; C. as measured using a differential scanning calorimetry method; a percent (%) haze of less than 3.5% and a % transmission of greater than 80% as measured using a method of ASTM D 1003-07, and wherein the blend composition possesses 80% or greater ductility in a notched izod test at &#x2212;20&#xb0; C. at a thickness of 0.125 inches according to ASTM D256-10.

Heat resistant clear polycarbonate-polysiloxane compounds

The present disclosure describes polycarbonate-siloxane blends with a constant percentage of siloxane in the formulations. The polycarbonate-siloxane blends achieve improved impact properties, as well as the ability to achieve deep black and bright white colors.

Low temperature impact properties in PC-siloxane copolymer blend with black and white color capacity

Disclosed herein are polydiorganosiloxane-polycarbonate block copolymers having desirable optical properties, and methods of making such block copolymers. Also disclosed herein are analytical methods for evaluating hydroxyaryl end-capped polydialkylsiloxane monomers.

Polydiorganosiloxane-polycarbonate block copolymers

Described herein is a thermoplastic composition comprising a polycarbonate, a mineral filler, inorganic acid or acid salt, an anti-drip agent, and a flame retardant comprising a perfluoroalkyl sulfonate salt or a combination of an aromatic phosphate ester and a polycarbonate-siloxane block copolymer.

Flame retardant thermoplastic polycarbonate compositions and films made therefrom

Disclosed herein are compositions including a polycarbonate-siloxane copolymer and a silicone-based graft copolymer. The compositions may include one or more additional polymers, such as a bisphenol-A polycarbonate. The compositions may include additional components, such as anti-drip agents, and/or flame retardant salt additives. Also disclosed herein are articles including the compositions, methods of using the compositions, and processes for preparing the compositions.

Polycarbonate-siloxane copolymer flame retarded with a silicone based core shell modifier

Disclosed herein are polysiloxane-polycarbonate copolymer articles. In one embodiment, a &#x215b;inch thick bar formed from the thermoplastic composition has a B-Y ratio of less than or equal to about 1.75. This article, which has a dimension that is greater than or equal to 1.5 cm, comprises the thermoplastic composition which comprises a polysiloxane-polycarbonate copolymer, wherein the copolymer comprises repeating diorganosiloxane units of formula (1): wherein each R is, independently, a Cmonovalent organic group; and E has an average value of 20 to 35.

Polysiloxane-polycarbonate copolymer article

A polycarbonate composition comprising a polycarbonate-polysiloxane copolymer resin and a glass flake additive wherein the polycarbonate-polysiloxane copolymer resin has a silicone content in the range of from 3.5 weight % to 7 weight % based on the total weight of the polycarbonate composition and wherein the polycarbonate-polysiloxane copolymer has a haze of less than 10% and wherein the glass flake additive is present in the range of 0.025 weight % to 0.70 weight % based on the total weight of the polycarbonate composition.

Highly ductile polycarbonate composition having a metallic-flake appearance

A method to reduce haze in the production of fire resistant polycarbonate compositions comprising flame retardant salts, wherein the salt is blended with a first polycarbonate to form a concentrate, and the concentrate is then added to a second polycarbonate resin.

Method for reducing haze in a fire resistant polycarbonate composition

A method is provided for making siloxane polycarbonate copolymers and blends of other polycarbonates with such copolymers wherein the copolymers and blends have excellent transparency and physical characteristic.

Transparent and high-heat polycarbonate-polysiloxane copolymers and transparent blends with polycarbonate and a process for preparing same

A fire retardant polycarbonate composition comprises branched polycarbonate resin, polytetrafluoroethylene, a fire retardant free of bromine and chlorine, and an optional siloxane.

Translucent flame retardant polycarbonate compositions

Improved fire-retarded properties can be imparted to polycarbonate resin composition by incorporating into the polycarbonate a fire-retardant component containing a perfluoroallkane sulfonate such as potassium perfluorobutane sulfonate and a cyclic siloxane such as octaphenylcyclotetrasiloxane. The fire-retardant component is suitably added at levels to form a polycarbonate composition in which the perfluoroalkane sulfonate is present in an amount of from 0.02 to 0.1 phr relative to the composition as a whole, and the cyclic siloxane is present in an amount of at least 0.02 relative to the composition as a whole.
