Received Date: 22 September 1992

Fund Project: Supported by National Natural Science Foundation of China.

A new Schiff base diol,4,4'-[3-methoxy-4-(2-hydroxy)-ethoxy] azomethine biphenyl (MHAMB),was synthesized,which was copolynerized with PEC-600 and TDI to obtain a blook polyurethane.The monomer and the polymer were charaoterized by eaploying IR,NMR and elemental analysis,Liquid crystallline phase transitions were studied by polarized aiorograph.
