3-(4-vinylphenyl)pyridine (3VPPy) and 4-(4-vinylphenyl)pyridine (4VPPy) that have amphiphilic property, which were synthesized by Suzuki coupling reaction have been polymerized with (diphenylmethyl)potasium (Ph2CHK) in tetrahydrofuran (THF) by anioinic polymerization. The polymerzation of 3VPPy and 4VPPy proceeded quatitatively of 3VPPy carried out 0 �C for 360 min and that of 4VPPy carried out quantitatively at -78 �C for 900 min and at -45 �C for 360 min. The well-defined poly(4VPPy) with predictable molecular weights and narrow molecular weight distrubution (Mw/Mn = 1.04 - 1.10) was obtainged, and poly(3VPPy) possesses predictable molecular weights and slightly broad molecular weight distributions (Mw/Mn = 1.13-1.18). The block copolymerization of 4VPPy with 2-vinylpyridine and methyl methacrylate (MMA) was performed to estimate the reactivity of homopolymer and to find its living nature. Additionally, each homopolymer was observed their self-assembly behavior in mixed solvent (THF and water) by SEM.
