摘要

An x-ray analysis of stretched oriented fibers of polyurethanes TDI-CmCn, derived from various mesogenic alkylene di$LB@4-(w-hydroxyalkyloxy-4-oxybenzoyl)oxybenzoate$RB@s (CmCn) and 2,4-toluenediisocyanate, is reported. The structure of two sequential nematic mesophases, a cybotactic nematic, and a conventional nematic mesophase is evidenced.
