摘要
Polycarbonates are formed by the interaction of a bisphenol diester, carbon monoxide and oxygen. The initial polycarbonate product is an oligomer which, upon heat treatment, polymerizes to a high molecular weight polycarbonate. The products produced according to the present invention are chainstopped prior to heat treatment, making them less thermally and oxidatively sensitive.
