Disclosed herein is a polymer blend comprising a first polycarbonate comprising a first structural unit derived from a 2-aryl-3,3-bis(4-hydroxyaryl)phthalimidine and a second structural unit derived from a dihydroxy aromatic compound, wherein the second structural unit is not identical to the first structural unit, and a second polycarbonate comprising a structural unit derived from a dihydroxy aromatic compound, wherein the polymer blend has a glass transition temperature of 155 to 200&#xb0; C.; and wherein a test auricle having a thickness of 3.2 mm and molded from the blend has a haze of less than or equal to 3.0 measured in accordance with ASTM D1003-00. A method of making the polymer blend, and articles prepared from the blend, are also disclosed.

High heat polycarbonates, methods of making, and articles formed therefrom

A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.

Diffuser for flat panel display

A film comprising in admixture a thermoplastic resin component comprising a thermoplastic resin component and a glass having a refractive index within 0.04 of the thermoplastic resin component, wherein the film has a haze of less than about 20%, total transmittance of greater than about 70%, and a coefficient of thermal expansion of about 20 to about 80 um/m/&#xb0; C. measured over a temperature range of 20 to 70&#xb0; C. The films are of particular utility in optical applications such as light diffuser films.

Transparent films, compositions, and method of manufacture thereof

A light collimating and diffusing film and a method for making the film are provided. The film includes a plastic layer having a first side and a second side opposite the first side and at least a first peripheral edge. The first side has a first textured surface, wherein between 7 to 20 percent of slope angles on the first textured surface proximate a first axis has a value between zero and five degrees. The first axis is substantially parallel to the first peripheral edge. The plastic layer collimates light propagating therethrough.
