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 thermoplastic composition comprises a polycarbonate, an ionizing radiation stabilizing additive, and a poly-substituted aromatic compound of formula: wherein X is an aryl group; Y is a non-hydrogen substituent group, a is 1 to 4, b is 0 to 4, a+b is less than or equal to 4, and c is 0 or 1; and wherein the amounts and identities of the polycarbonate, ionizing radiation stabilizing additive, and poly-substituted aromatic compound are selected such that a molded article having a thickness of 3.18 millimeters and comprising the thermoplastic composition has, after exposure to gamma radiation at 83 kGy and when measured according to ASTM D1925-70, an increase in yellowness index (dYI) of less than or equal to 50, when compared to the unexposed thermoplastic composition.

Stabilized thermoplastic composition, method of making, and articles formed therefrom

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 composition includes a polycarbonate-polysiloxane block copolymer that has at least one polycarbonate block and at least one polysiloxane block, and a surface modifying agent that includes at least one polysiloxane segment. Increased levels of the surface modifying agent can be incorporated without compromising high transmittance and low haze. The compositions also exhibit improved hemocompatibility and are therefore useful for a variety of articles that may contact blood.

Transparent polycarbonate-polysiloxane copolymer blend, method for the preparation thereof, and article derived therefrom

A polyester molding composition reinforced with fiber glass or other silica based filler which has color stability at relatively high temperatures and comprises (a) from 40 to 97 weight percent of a polyester resin; (b) from about 3 to about 60 weight percent fibrous glass or silica based filler or mixture; (c) less than about 5 percent by weight additional ingredients which include a combination of stabilizers consisting essentially of an acidic quencher, a thioester and a phosphonite and (d) optionally from 2 to 30 weight percent of a flame retarding composition.

Glass filled polyester compositions with improved color stability

A method for making an impact modified thermoplastic resin composition includes combining an glycidyl ester impact modifier with a polycarbonate resin to form a glycidyl ester impact modifier-polycarbonate resin blend and then combining the glycidyl ester impact modifier-polycarbonate resin blend with a polyester resin to provide the impact modified thermoplastic resin composition. Articles molded from the impact modified thermoplastic resin composition made according to the method exhibit high impact resistance and improved surface appearance.
