Abstract
This study reports new functionalized material for biomaterial. The polymeric micelles were studied by many researchers for addition of function. Therefore, we designed a block polymer to have hydrophilic and hydrophobic segments by hybrid polymerization. It would be expected the capacity to respond to stimulus voluntarily and autonomously.
Hybrid polymerization was performed by a combination of ring opening polymerization of TMC and living radical polymerization of two types of multifunctional vinyl monomers, namely, N-isopropylacrylamide (NIPAAm) and 2-methacryloyloxyethyl phosphorylcholine (MPC). Copolymerization with NIPAAm and MPC from the macro-initiator using poly(trimethylene carbonate) was successfully achieved. The resulting polymer was characterized by structural analysis of 1H-NMR, GPC, and IR. In addition it spontaneously formed self-aggregation in water. This hybrid polymerization approach is capable of producing polymer micelles with versatile hydrophilic segment.
