Abstract
Blended polymer compositions are described which comprise: (A) at least one amorphous polycarbonate; and (B) at least one linear polycarbonate oligomer containing hydroquinone carbonate structural units. The blended polymer compositions having particular application in the preparation of shaped articles for use in environments characterized by the presence of solvents, solvent vapors, and/or potential for fire conditions. Methods for increasing the solvent and flammability resistance of amorphous polycarbonates are also described.
