Outline of Final Research Achievements

First, Novel biobased and biodegradable polymers were synthesized from furfural produced from inedible biobased resources and their physical properties and biodegradability were evaluated.
Next, two kind of biobased-biodegradable polymers with functional groups on the end, which had complementary interaction, were synthesized. Self-assembly process formed by the complementary interaction between the functional groups on the end of polymer chain constructed supramolecular-biodegradable polymer of which higher-order structure was controlled by the interaction. Self-assembly process was evaluated by NMR spectra (DOSY spectra) and differential scanning calorimetry (DSC).
Furthermore, external stimuli deteriorated the supramolecular structure and this behavior indicates that the biodegradability of supramolecular- biodegradable polymer can be controlled by extra stimuli in environment.
