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(l) 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/cm2). The log G' against temperature curves for both samples decrease with increasing temperature upto transition temperature and then increase upto TCand then decrease again with increasing temperature above TCshowing maxima at around Tc.
