Process for producing polycarbonate |
摘要 |
Provided is a simple and economical method for producing high-quality polycarbonates having a high degree of polymerization and therefore having an increased molecular weight. The method comprises preparing oligocarbonates through oxidative carbonylation of an aromatic hydroxy compound with carbon monoxide and oxygen followed by increasing the molecular weight of the oligocarbonates through transesterification to produce polycarbonates having an increased molecular weight.
