Transesterification process for preparation of linear polyesters |
摘要 |
An improved transesterification process for preparation of a linear aromatic polyester comprising bisphenol and dicarboxylic acid monomer units terminated with a carboxylic acid ester groups derived from a long chain aliphatic monofunctional alcohol comprises as the improvement partially transesterifying a diaryl ester of the dicarboxylic acid with the alcohol prior to carrying out the transesterification polymerization reaction of said aryl ester and the bisphenol.
