## Abstract The conformations of thermotropic polyesters with alternating mesogens and poly(methylene) spacers in the main chain were investigated by conformational calculations using the data of linearβdichroism IRβspectroscopy, Xβray analysis and differential scanning calorimetry. The conformatio

## SYNOPSIS Four series of thermotropic polyurethane elastomers (TPUEs) were synthesized in this study. The hard segments were formed by using 4,4'-methylenedicyclohexyl diisocyanate (H,,MDI) reacted with various mesogenic units, such as benzene-1,4-di(4-iminophenoxyn-hexanol), benzene-1,4-di(4-im
