| Research Abstract |
Development of high-thermoresistance biopolymers is a challenging subject in the field of bioplastics indispensable for establishment of sustainable society. in this study, we selected 3-amino-4-hydroxybanzoic acid (34AHBA) and its derivative which is originated from Streptomyces griceus as a starting material, and synthesized rigid-rod polymers with a benzoxazole structure inducing efficiently to high-thermoresistance. Actually oxidized derivative of 34AHBA, 3-amino-4-hydroxybenzaldehyde (34AHBAL), was modified to prepare a kind of hydroxyamines which is a monomer of polybenzoxazoles (PBO). Finally PBO film with a high-thermoresistance temperature and LC-functional PBO were successfully prepared.
