| Outline of Final Research Achievements |
Mesogenic monomers and side-chain polymers with reactive groups such as oxazoline, aziridine, and epoxy groups were synthesized. Various liquid-crystalline polymers were obtained using the ring-opening reaction. The side-chain polymers with oxazolylbiphenyl groups exhibited liquid-crystalline phases on heating and cooling processes. A side-chain polymer having oxazolylphenyl groups easily reacted with sebacic acid at the liquid state. The resultant polymers, which are a cross-linked polymer, formed a nematic phase. A polymer (Poxa-1), in which an oxazolyl group directly linked to the polymer backbone, was synthesized. Novel liquid-crystalline blocked copolymers were obtained by the reaction of Poxa-1 and a liquid-crystalline polymethacrylate with a carboxyl group at the terminal. The ring-opening reactions led to the development of the novel liquid-crystalline polymeric systems.
