STUDIES ON THE MORPHOLOGY OF THERMOTROPIC POLYESTER DURING TRANSITIONS BETWEEN ISOTROPIC AND ANISOTROPIC MELTS

Received Date: 20 May 1988

The morphology of a thermotropic aromatic polyester during the transitions between isotropic and anisotropic melts was studied by means of polarizing microscopy and small angle light scattering techniques. Both transition processes were found to be composed of the initiation of a new phase at local places of the old phase matrix and the growth of the new phase domains. A change of Hv scattering patterns was observed in the transition temperature ranges and was explained as the result of heterogeneity of the mesophase system,but not the change in ordering of a homogeneous mesophase.
