    摘要: Disclosed herein is a method of preparing a polycarbonate composition comprising melt blending a first polycarbonate prepared by interfacial polymerization and having hydroxy end groups that are capped with endcapping groups, with a second polycarbonate prepared by melt polymerization and having hydroxy end groups that are capped with endcapping groups, wherein the second polycarbonate has a lower mole percent of endcapping groups than that of the first polycarbonate; wherein an article having a thickness of 3.2 mm and molded from the polycarbonate composition has a haze of less than 3 according to ASTM D1003-00; and wherein a flat article molded from the polycarbonate composition has a surface charge of −2 to +2 kV. A polycarbonate composition and complex article prepared according to the method are also disclosed.
