A copolycarbonate optical article comprises a polycarbonate composition including: a copolycarbonate having: 2 to 60 mol % of phthalimidine carbonate units, 2 to 90 mol % of high heat carbonate units, and optionally 2 to 60 mol % of bisphenol A carbonate units. The copolycarbonate has less than 100 ppm of each of phthalimidine, high heat bisphenol, and bisphenol A monomers, and less than 5 ppm of various ions, and is prepared from monomers each having a purity of at least 99.6%. The polycarbonate composition has a glass transition temperature of 200&#xb0; C. to and a yellowness index of less than 30.

Phthalimidine copolycarbonate optical articles, articles formed therefrom, and methods of manufacture

High purity epoxide compounds methods for preparing the high purity epoxide compounds, and compositions derived from the epoxide compounds are provided. Also provided are materials and articles derived from the epoxide compounds.

High heat monomers and methods of use thereof

High purity epoxide compounds, methods for preparing the high purity epoxide compounds, and compositions derived from the epoxide compounds are provided. Also provided are materials and articles derived from the epoxide compounds.

Melt polymerization processes for producing photoactive additives are disclosed. The photoactive additives are cross-linkable polycarbonate resins formed from a benzophenone, a dihydroxy chain extender, a carbonate precursor, and a catalyst. The additives can be produced without the use of phosgene or dichloromethane, and can be cross-linked with other polymers upon exposure to UV radiation.

Melt reaction process for crosslinkable polycarbonates

This disclosure relates to polycarbonate compositions, methods, and articles of manufacture that at least meets certain electrical tracking resistance requirements. The compositions, methods, and articles of manufacture that meet these requirements contain at least a polycarbonate; a polysiloxane block co-polycarbonate; and a transition metal oxide, e.g. titanium dioxide.

Electrical tracking resistance compositions, methods and articles of manufacture

A core-shell particle is formed by a method that includes forming a crosslinked polyorganosiloxane core, reacting a graftlinking agent with the crosslinked polyorganosiloxane core, and polymerizing a poly(alkenyl aromatic) shell around the graftlinking agent-functionalized polyorganosiloxane core. The method produces a core-shell particle with improved adhesion between shell and core. The core-shell particle is useful as an impact modifier in thermoplastic compositions.

Core-shell particle, method, and composition

An article comprises a compatibilized poly(arylene ether)/polyamide blend, an optional electrically conductive filler, a phosphinate, and flame retardant augment selected from the group consisting of melamine polyphosphate, zinc borate, low melting glass, talc, and combinations of two or more of the foregoing flame retardant augments.

Flame retardant thermoplastic article

A flame retardant poly(arylene ether)/polyamide composition includes a poly(arylene ether), a polyamide, about 5 to about 15 weight percent glass fiber, and a flame retardant consisting of a metal dialkyl phosphinate. Methods of preparing the composition are described, as are articles that include it.
