제목 Comparison for Micelle Formation of Amphiphilic Star Block Copolymers
초록 To compare the micelle formation of amphiphilic star block copolymers, we prepared amphiphilic polyethyleneglycol (PEG) and poly (trimethylene carbonate) (TMC) star block copolymers via ring-opening polymerization of trimethylene carbonate (TMC) monomer initiated at the hydroxyl end group of the core PEG using HCl Et2O as a monomer activator. The amphiphilic nature of the segments of these PEG-b-PTMC star block copolymers gave micelles with a coreshell structure in an aqueous phase. Most of the micelles prepared from amphiphilic PEG-b-PTMC star block copolymers were spherical. With increasing arm number, the mean hydrodynamic diameters of micelles and CMC increased. In conclusion, we found that amphiphilic PEG-b-PTMC star block copolymers is potential hydrophobic drug carriers. Acknowledgements: This study was supported by a grant from MKE (Grant no. 10030022).
