ABSTRACT:
Poly(ester aromatic dihydric alcohol) polymers having carbonate moieties, aromatic or cycloaliphatic dicarboxylic acid moieties and carbonate moieties and having high glass transition temperatures (over 100.degree. C.) and being melt processable. At least part of the aromatic dihydric alcohol moieties have the 4-carbon of each of two phenoxies covalently bonded to the same ring carbon of a carbocyclic or heterocyclic moiety. Representative poly(ester carbonates) are formed from bisphenol-A, phenolphthalein, terephthaloyl chloride and phosgene.
