Main-chain type thermotropic liquid crystalline polymers HPC-P having lower liquid crystalline temperature were obtained by esterification of hydoxypropyl cellulose. Two different samples were obtained, the one is HPC-P(1) having DS=2.4 and another one is HPC-P(2) having DS=2.8. Logarithmic curves of dynamic modulus(G’) and loss modulus((G ") against frequency obtained at different temperatures within liquid crystalline temperature range can be superposed to obtain a single composite curve for both samples. The composite curves for G’ show lower frequency side plateau (Ca. 300 dyne/cm(2)). The log G’ against temperature curves for both samples decrease with increasing temperature upto transition temperature and then increase upto T-C and then decrease again with increasing temperature above T-C showing maxima at around T-C.
