Abstract

Aromatic polyester (PEA) and copolyesters having pendant carboxyl groups aredirectly synthesized from isophthaloyl chloride, diphenolic acid and diols byaqueous/organic two-phase interfacial polycondensation, using phase transfercatalysts. The yield and molecular weight of the polyester were remarkablyaffected by the structure of quaternary ammonium salts and crown ether catalysts.The phase transfer reaction steps are suggested to explain this phenomena. Theproperties of copolyesters were dependent on the original structure of diols.
