Novel Polyesters were succesfully synthesized by palladium catalyzed carbonylative polycondensation of xylene dibromides and various diols with carbon monoxide. The effects of reaction variables, such as catalysts, bases, solvents, carbon monoxide pressure, and reaction temperature, were discussed in detail for the reaction of p-dibromoxylene and 2, 2-bis(4-hydroxyphenyl)propane with carbon monoxide. The polyesters were characterized by IR, elemental analysis, GPC, DSC, TGA, and polarizing microscope.
