Claim Text:
1. A blended polycarbonate composition with improved heat resistance comprising: (a) from about 0 pph to about 90 pph of a first polycarbonate polymer; (b) from about 1 pph to about 90 pph of a second polycarbonate polymer, wherein the second polycarbonate polymer is a high heat polycarbonate polymer and is a copolymer of bisphenol A and 4,4′-(1-phenylethylidene)bisphenol; (c) from about 1 pph to about 25 pph of at least one impact modifier composition; (d) from about 0 pph to about 25 pph of a polystyrene acrylonitrile copolymer; (e) from about 0 pph to about 25 pph of a flame retardant; and (f) pph balance of one or more of a polymer composition additive.
