STATISTICAL MODELS FOR SEMI-RIGID NEMATIC POLYMERS*

WANG Xinjiu

Received Date: 1 September 1994

Semi-rigid liquid crystal polymer is a class of liquid crystal polymers different from long rigidrod liquid crystal polymer to which the well-known Onsager and Flory theories are applied. Inthis paper, three statistical models for the semi-rigid nematic polymer were addressed. They arethe elastically jointed rod model, worm-like chain model, and non--homogeneous chain model.The nematic-isotropic transition temperature was examined. The pseudo-second transition tem-perature is expressed analytically. Comparisons with the experiments were made and the agreements were found.
