Abstract
Phase transition behavior of thermotropic liquid crystalline polymers under hydrostatic pressure has been studied by using a high-pressure DTA and a wide angle X-ray scattering equipment for high temperature and hydrostatic pressure. Phase diagrams of some main-chain thermotropic polyesters have been reported. Some experimental results of pressure-induced crystal polymorph and pressure-induced liquid crystalline phase of main-chain thermotropic polyesters are described.
