Synthesis and Evaluation of MPEG-Polyester Block copolymer with functional group |
초록 |
MPEG-b-PCL as a thermo-responsive polymer holds great promise in biomedical applications. However, MPEG-b-PCL has not functional group with side chain, and thereby limited to application. Overcome this problem, we introduced functional group in PCL backbone to enhance facilitate a variety of applications. We synthesized of amphiphilic MPEG-b-PCL based-block copolymers bearing functional side groups on the PCL block by ring-opening polymerization. The thermal properties (Tg and Tm) 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 may potentially be used as thermo-responsive in situ gel-forming systems. |
