Eleven polyesters and polyamides are synthesized by polycondensation of diacid chloride of 1,2-bis(4'-carboxy-phenoxy)ethane with different dihydroxy compounds and diamines.All the polyesters exhibit mesomorphism.Aliphatic-aromatic polyamides are mesogenic whereas, aromatic polyamides are non-mesogenic.Polymers are characterized by elemental analysis and IR spectra.The viscosity of soluble polymers is measured.The effect of chemical constitution and viscosity on mesomorphism is evaluated.One branched chain polyester exhibits nematic mesophase at room temperature and is quite stable with a long mesophase range.The thermogravimetric analysis is carried out to evaluate the thermal stability of one of the samples.
