A transparent, flame retardant polycarbonate composition consisting essentially of an aromatic polycarbonate resin and a flame-retarding amount of a guanidine salt or derivatives thereof, wherein the amount of guanidine salt or derivatives thereof is about 1 wt. % or less.

Polycarbonate resin compositions and articles therefrom

Disclosed herein is a light diffusing substrate in the form of film or sheet including multi-wall sheet and a process for making such light diffusing article, wherein the article comprises a light transmitting thermoplastic resin and about 0.001 to 10 wt. parts of a polyalkyl silsesquioxane, wherein the alkyl group is selected from a methyl, a C12-C18 alkyl, hydride, phenyl, vinyl, and cyclohexyl. The light diffusing substrate is characterized as having a surface roughness expressed as a centerline average height Ra of about or less than 0.1 &mgr;m, a ten-point surface roughness Rz of about or less than 1.0 &mgr;m, and a maximum height surface roughness Rmax of about or less than 1.0 &mgr;m.

Light diffusing articles and methods to manufacture thereof

The present invention relates to flame retardant polycarbonate compositions with improved weathering performance, said compositions comprising one or more cyanoacrylic esters. The invention also relates to methods for improving the flame retardancy and weathering performances of polycarbonate compositions by incorporating cyanoacrylic ester(s). Finally, the invention further relates to articles manufactured from flame retardant polycarbonate compositions comprising cyanoacrylic ester(s).

Flame retardant polycarbonate compositions with improved weathering performance containing cyanoacrylic esters

A transparent, fire resistant polycarbonate composition comprises polycarbonate, poly(methylphenylsiloxane) and a salt based flame retardant. These polycarbonate compositions can attain UL94 V0 ratings at 1.6 millimeter thickness, previously possible only with a halogenated fire retardant.

Transparent, fire-resistant polycarbonate

A transparent/translucent flame redardant composition comprises a uniform blend of a miscible resin blend of a polycarbonate resin and a cycloaliphatic polyester resin wherein the composition has at least a 80% pass rate in 10 test specimen in the Norme Francaise NF-P-92-505 flammability test of L'Association Francaise de Normalisation using test specimens with weight between about 1.0 to about 6.0 kilograms per square meter.

Flame retardant polycarbonate polyester composition

The invention relates to a method for the production of a branched polycarbonate composition, having increased melt strength, by late addition of branch-inducing catalysts to the polycarbonate oligomer in a melt polycondensation process. Surprisingly, it has been found that by adding branch-inducing catalysts, such as alkali metal compounds and/ or alkaline earth metal compounds, to the melt polycarbonate oligomer at a later stage of the melt polycondensation process, preferably after the oligomer has reached an average molecular weight of between about 3,000 and 30,000 g/mole, a unique branched polycarbonate composition is formed that has improved properties. It is believed that the addition of the branch-inducing catalysts at the later stages of the process produces a branched polycarbonate composition having longer chains between the branching points, and thus a new composition is produced. The invention also relates to various applications of the branched polycarbonate composition.

Process for the production of branched melt polycarbonate by late addition of fries-inducing catalyst

Translucent polycarbonate compositions include an aromatic polycarbonate, a cycloaliphatic polyester, and a polyolefin. The compositions have excellent optical characteristics and superior physical properties, particularly low-temperature impact strength, compared to translucent polycarbonate-polyester blends requiring inorganic fillers.
