Syntheses of aromatic polyesters from silylated monomers

Summary Aromatic polyesters were synthesized either from silylated bisphenols and diacid chlorides or from trimethyl siloxy benzoyl chlorides by thermal condensation at 200–300°C. Yields and molecular weights were compared with those obtained by other condensation methods. The Silyl Method seems to be most useful for the synthesis of polyesters of aromatic -hydroxy acids.
