    摘要: Processes for preparing polyestercarbonates are disclosed. The processes allow for the consistent incorporation of adipic acid into a polymer generated from a dihydroxy compound, such as bisphenol-A, at levels greater than 99%. The polyestercarbonates so produced, as well as articles formed from the polyestercarbonates, are also disclosed herein.
