ABSTRACT:
There are described linear aromatic polyesters of a bisphenol and a dicarboxylic acid having terminal carboxylate ester substituents of an aliphatic monofunctional alcohol of 8 to 45 carbons. The polyesters have enhanced hydrolytic stability compared to conventional polyesters of bisphenol and a dicarboxylic acid. Low molecular weight polyesters of the invention have improved stability on processing compared to comparable conventional polyesters of a bisphenol and a dicarboxylic acid. Processes for preparing the polyesters are also disclosed.
