Amphiphilic block copolymers have a rich phase behavior and their phase behaviors are easily controlled by the external condition, that allows a wide range of applications. Depending on the molecular weight distribution (Mw) of block copolymers, however, their phase behaviors are readily affected, leading to the limitation of the various applications. The ring-opening polymerization is one of the most effective methods to obtain a block copolymer with a narrow Mw. In general, to synthesize block copolymers with a narrow Mw by the ring-opening polymerization, the control parameter such as the reaction time and temperature is crucial. Furthermore, the control parameter also depends on the block types and the combinations of blocks. Here, we have investigated to obtain the experimental condition for synthesizing amphiphilic diblock copolymers with a narrow Mw(＜1.02), where the hydrophilic block is the poly(ethylene oxide) and the hydrophobic block is based on the glycidyl ether group. |
