Séminaire par Hiroharu AJIRO / Nara Institute of Science and Technology
Mardi 5 Février 2019 - 15h - Salle Maroni / MHT
Hiroharu Ajiro, Professeur au Nara Institute of Science and Technology fera une présentation intitulée: Poly(trimethylene carbonate) derivatives bearing oligo(ethylene glycol) with ester free structure and polylactide stereocomplex with functional chain-end groups.
We designed the functional biodegradable polymers with ester free structure, in order to avoid the acidic compounds generation after hydrolysis. We selected trimethylene carbonate (TMC) as a monomer, and the functional group was introduced as a side group. For example, we introduced oligo(ethylene grlycol) (OEG) units as a thermoresponsive group.
The copolymerization of TMC derivatives gave hydrophilic-hydrophobic block copolymer, and it was used for thin film preparation. The hydrogel was also prepared for the possible biomedical applications. We also utilized polylactides with functional chain-end groups and stereocomplex formation in order to apply medical polymer materials.
