摘　　要：New poly(azomethine-ether)s PAMEs containing 1-phenethyl-4-piperidone moiety have been synthesized through a solution polymerization of various diformyl-a,w-diphenoxyalkanes,I-IV with 3,5-bis(p-aminobenzylidene)-1-Phenethyl-4-piperidone VI.The structures of these polymers were confirmed using spectroscopic techniques.The inherent viscosities of the resulting polymers were found to range from 0.65 to 0.95 dl/g.The solubility of the PAMEs was estimated,showing good solubility in aprotic solvents.The thermal properties of the PAMEs were also evaluated by DSC technique.Liquid crystalline state of the polymers was observed on polarizing microscope exhibiting nematic phase for most of the synthesized polymers.
