内容記述 |
Poly(trimethylene carbonate) (PTMC) derivatives have been extensively researched for use as low-toxicity biomaterials. Better biocompatibility and lower toxicity have been achieved by eliminating acid generation from the ester group at the side chains. In this study, thermosensitive PTMC derivatives bearing oligo(ethylene glycol) units were synthesized by ring-opening polymerization for the development of low-toxicity and thermosensitive soft materials. The viscoelastic properties of the obtained polymers were then investigated by rheometry to clarify the thermosensitive and molecular weight effects. Furthermore, thermosensitive behaviors and dynamics of these polymers were observed by UV-vis transmittance, DSC, and 1H NMR spectra analysis. These data suggest a mechanism for the thermosensitive behavior where it was surmised that some kind of dehydration phenomena induced aggregation behavior in aqueous media above lower critical solution temperature (LCST). These thermosensitive behaviors provide an important road map for the development of thermosensitive soft materials using ester free PTMC derivatives by controlling the thermosensitive behaviors and bulk properties. |
