AROMATIC POLYCARBONATES AND PROCESS FOR THEIR PRODUCTION

摘要

Provided are polycarbonates excellent in hue and stability and a process for producing the same. In producing a polycarbonate by melt-polycondensing a dihydroxyl compound with a carbonic diester in the presence of a transesterification catalyst, the aldehyde contents of the dihydroxyl compound and the carbonic diester are each adjusted to 3 x 10<-6> equivalent/mol or below.
