Abstract
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.
