| Outline of Final Research Achievements |
We tried to make sure the origin of resin character of a novel non-ester type bio-based polymer, poly(a-methylene-g-butyrolactone) (PMBL) through chain dimension analysis in the solution state and physical characters in the thin film state. The characteristic physical properties is originated from the low free volume and high inter-chain interaction, whereas the chain stiffness is not dominant for the resin character. We also investigated the thin film mechanical properties through microscopic compression test by the use of scanning probe microscopy and macroscopic friction test. We could demonstrate the excellent mechanical properties of the PMBL brush-type thin films.
