Anionic Polymerization of Amphiphilic Polymer Containing Pyridine Moiety |
| 초록 |
Amphiphilic monomer, 2-(4-vinylphenyl)pyridine (A), 3-(4-vinylphenyl)pyridine (B), and 4-(4-vinylphenyl)pyridine (C) has been synthesized by Suzuki coupling reaction. Anionic polymerization of these monomer carried out with (diphenylmethyl)potassium (Ph2CHK) in tetrahydrofuran (THF). The polymerization of A and C proceeded quantitatively at 78 °C for 150 min and 900 min. The well-defined poly(A) and poly(C) with predictable molecular weights and narrow molecular weight distributions (Mw/Mn = 1.041.10) was obtained, but the polymerization of B carried out quantitatively at 0 °C for 360 min, and poly(B) possesses predictable molecular weights and slightly broad molecular weight distributions (Mw/Mn = 1.131.18). The block copolymerization of A and C with 2-vinylpyridine and methyl methacrylate was performed to estimate the reactivity of homopolymer and to find its living nature. |
