摘要：
Liquid-crystalline polyesters have been prepared from the mesogenic unit 4,4'-dihydroxybicyclohexyl and linear aliphatic diacids, which served as a flexible spacer. The polymers were characterized by optical microscopy, thermal analysis, X-ray diffractometry, and conformational analysis. The polymers have been assigned as passing through the following thermotropic transition sequences: crystal-smectic G-isotropic. This behavior is compared with that of the corresponding polymers prepared from 4,4'-dihydroxybiphenyl.
