摘要：
A wholly aromatic polyester carbonate having a satisfactory color tone and excellent thermal stability. This polymer has an alkali metal content as low as 10 ppm or below. The polymer is advantageously produced by reacting an aromatic dicarboxylic acid, an aromatic diol, and a diaryl carbonate in a specific molar proportion using a pyridine compound as a catalyst.
