Method for preparing polycarbonates of enhanced crystallinity |
| abstract |
Crystallinity of amorphous precursor polycarbonates is enhanced by contact with at least on diaryl carbonate such as diphenyl carbonate, followed by pelletization and heating to a temperature above the melting point of the diaryl carbonate and below the glass transition temperature of the amorphous precursor polycarbonate. The crystallinity enhancement operation may be conducted in the presence of dihydroxyorganic monomers and may be followed by a solid state polymerization operation. |
