Outline of Final Research Achievements

The aims of this study are the production of new biomass-based plastics from non-edible biomass and the high-functionability of these plastics. A new crystal agent was developed for poly(lactic acid) stereocomplex. Novel crystalline polyesters and polyamides were succeeded to synthesize from glucalic acid, one of fundamental bio-based monomers. Furthermore, two kinds of copolymers were synthesized from ferulic acid. On the other hand, ultra-high-molecular-weight microbial polyesters have been synthesized and succeeded to process the high tensile strength fibers by blending to normal molecular weight microbial polyesters. The molecular and crystals structures were analyzed by the X-ray diffraction at synchrotron radiation.
