Synthesis and Self-Assembly of Amphiphilic Homopolymer and Blockcopolymer Containing 4-(4-Vinylphenyl)pyridine |
| 초록 |
The anionic polymerization of 2-(4-vinylphenyl)pyridine (A), 3-(4-vinylphenyl)pyridine (B), and 4-(4-vinylphenyl)pyridine (C) has been 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. 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. The resulting block copolymers of poly(A)-b-PMMA showed micro-phase separation in THF as observed from TEM. It was finally confirmed that the morphologies of poly(A)-b-PMMA were changed depending on block ratios of block copolymers. And the solubilities and thermal properties of the resulting poly(A) and poly(C) were investigated. |
