| 摘要 |
Copolycarbonates of enhanced crystallinity, suitable for solid state polymerization, are prepared by melt blending, under non-reactive conditions, an amorphous precursor polycarbonate such as a bisphenol A polycarbonate with one or more other monomers which may include a spiro(bis)indane bisphenol and/or a phenylindane bisphenol, optionally with a polyoxyalkylene glycol. The resulting blend is pelletized and the crystallinity of the resulting pellets is enhanced, typically by contact with an alkanol liquid or vapor.
