제목 Preparation and Characterization of Polyester diblock copolymer with functional group for in situ forming hydrogel
초록 MPEG-b-PCL as a candidate thermo-responsive polymer that featured favorable properties. However, MPEG-b-PCL has not functional group with side chain, and thereby limited to application. To solved this problem, we introduced functional group in PCL backbone to enhance facilitate a variety of applications. We synthesized of MPEG-b-PCL based-block copolymers with functional pendant groups on the PfCL block by ring-opening polymerization. The thermal properties of the block copolymers depend on the functional pendant group on PfCL composition. The derivatized MPEG-b-(PCL-co-PfCL) di-block copolymer solutions exhibited sol-to-gel phase transitions upon a temperature increase. The sol-to-gel phase transition depended on both the type of functional group on the PfCL and the PfCL content in the PCL segment. These results indicate that MPEG-b-(PCL-co-PfCL) di-block copolymer solutions could be used as thermo-responsive in situ gel-forming systems.
