Beschreibung
Zusammenfassung:	Disclosed herein are methods and compositions of polycarbonate blends having, among other characteristics, improved heat resistance. The resulting polycarbonate blends, comprising a first polycarbonate comprising structural repeating units derived from bisphenol acetophenone and optionally a second polycarbonate polymer comprising structural repeating units derived from bisphenol A, can be used in the manufacture of articles while still retaining the advantageous physical properties of blended polycarbonate compositions with improved heat resistance. The disclosed polycarbonate blends optionally comprise one or more polycarbonate blend additives. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
