    摘要: Polymer blend compositions are prepared having excellent combinations of optical properties, physical properties and hydrolytic stability comprising, in admixture, (a) a diaryl fluorene carbonate polymer and (b) a polysulfone. Preferably, the diaryl carbonate polymer is a copolycarbonate of bisphenol A with bis(hydroxyphenyl) fluorene, preferably 9,9-bis(4-hydroxyphenyl) fluorene. Optionally, the blend compositions also comprise a second non-fluorene carbonate polymer (c). Preferably, the polysulfone is a bisphenol A polysulfone or a polyether poly sulfone. In preferred aspects of this invention, the polysulfone and diaryl carbonate polymer components are selected to provide a transparent blend composition.
