A multilayer thermoplastic film having polycarbonate layers is disclosed, in which a first layer comprises a first polycarbonate that comprises repeat units derived from one or more of a monoaryl monomer (II) and/or (III), and a diaryl monomer (IV) as defined herein. A second layer, adjacent to the first layer and coextruded therewith, comprises another polycarbonate that is not the same as a polycarbonate in the first layer. The first layer provides improved properties, for example hardness, impact, and/or scratch resistance.

Multilayer films for insert mold decoration, methods for making the same, and articles made therefrom

The present invention provides methods for controlling the optical properties of a light transmissive article. The method includes identifying a target window in an Abbe diagram comprising reference polymeric materials. The method further includes selecting a first polymeric material from the reference polymeric materials and compounding the first polymeric material with a stable UV chromophore to provide a first polymer composition. The method further includes transforming the first polymer composition to provide the light transmissive article, wherein the light transmissive article has an Abbe number and a refractive index which falls within the target window. Light transmissive articles prepared using the above methods are also provided.

Light transmissive articles and methods thereof

A method of making a thermoplastic composition comprises melt blending a reaction mixture comprising a first polycarbonate comprising repeat units derived from monoaryl monomers (II) and (III) and a diaryl monomer (IV), wherein the sum of the mole percent of the repeat units derived from monomers (II) and (III) is greater than or equal to 30 mole percent, and the mole percent of the repeat units derived from monomer (IV) is 5 to 70 mole percent, each based on the total moles the repeat units derived from monomers (II), (III), and (IV), and the total weight of the repeat units derived from monomers (II), (III), and (IV) is greater than or equal to 90 wt. % of the first polycarbonate; and an additional polycarbonate, comprising 50 to 100 mole percent of repeat units derived from a bisphenol cyclohexane.

Methods for the manufacture of polycarbonate compositions, the compositions formed thereby, and articles thereof

Disclosed herein is an isosorbide-based polycarbonate polymer comprising: an isosorbide unit, an aliphatic unit derived from a Caliphatic diacid, Caliphatic diol, or combination of these; and a polysiloxane block.

Isosorbide-based polycarbonates, method of making, and articles formed therefrom

Disclosed herein is an isosorbide-based polycarbonate polymer comprising: an isosorbide unit, an aliphatic unit derived from a Caliphatic diacid, Caliphatic diol, or combination of these; and optionally, an additional unit different from the isosorbide and aliphatic units, wherein the isosorbide unit, aliphatic unit, and additional unit are each carbonate, or a combination of carbonate and ester units. Also disclosed are a thermoplastic composition and an article comprising the isosorbide-based polycarbonate.
