| Outline of Final Research Achievements |
We examined the development of novel biodegradable biomaterials using hight-pressure. First, the acid-catalysed ring-opening polymerization of gamma-butyrolactone (gamma-BL) was carried out in the presence of methanol as an initiator and trifluoromethanesulfonic acid as a catalyst. As the result, the monomer conversions increased with increasing pressures, indicating that high pressure conditions strongly affected the polymerization manner. Next, we performed the preparation of chitin nanoparticles by regeneration from a chitin/1-allyl-3-methylimidazolium bromide solution through high-pressure process. The morphology of nanoparticles was seen in the SEM image of the sample from the resulting dispersion.
