Abstract
A series of amphiphilic poly(vinyl ether)-based macromonomers having an aromatic ring, such as phenyl, naphthyl, and anthryl group, at ω-terminus (MA-PMEEVE-Ph, MA-PMEEVE-Nap, and MA-PMEEVE-Ant) were synthesized by living cationic polymerization and reductive amination. The obtained amphiphilic macromonomers possess narrow molecular distributions (Mw/Mn = 1.14–1.41) and well-controlled degree of polymerization (DPn ≈ 40). In addition, the functionality of the ω-terminus is equal to unity for all the macromonomers. Then, copolymerizations of the obtained macromonomers with styrene in polar solvents were performed to form nearly monodisperse polymer particles. In order to clarify the effect of the terminal hydrophobic group on particle formation behavior, we have investigated the relationships between the feed ratio of the macromonomers to styrene and particle diameter (Dn) and distribution of the particle diameter. As a result, MA-PMEEVE-Ant afforded the smallest polymer particle of Dn = 70 nm. It was also found that the particle diameter can be controlled by tuning the hydrophobicity of the ω-terminus group.
