Factors affecting the formation of high molecular weight aromatic polyesteramides by solution polycondensation

Fully aromatic polyesteramides from aminophenols and benzenedicarbonyl chlorides are synthesized by low temperature solution polycondensation. The optimum conditions for the polycondensation reaction are established through systematic study of the factors affecting the molecular weight of the result...

Description
Summary:Fully aromatic polyesteramides from aminophenols and benzenedicarbonyl chlorides are synthesized by low temperature solution polycondensation. The optimum conditions for the polycondensation reaction are established through systematic study of the factors affecting the molecular weight of the resulting polymers, which are reaction temperature, LiCl concentration, nature and concentration of the tertiary amine catalyst, water content in the solvent, concentration of the monomers, nature of solvent, rate of stirring and state of the acid chloride added.
