摘要

<,正,>, Two series of new liquid crystailine polymers with T-shaped two-dimensional mesogenicunits were synthesized by low temperature solution polycondensations of 4-substituted N-2, 5- dihydroxybenzylidene aniline monomers with different diacyl dichlorides. The polymerswere found to be nematic and shown liquid crystailine behavior. The melting temperatureT,m, and the clearing temperature T,i, of the polymers change regularly with varying of themonomer structures.
