Well defined PVA-b-PNVAm block copolymers via RAFT polymerization |
| 초록 |
Poly(vinyl amine)(PVAm) is a water-soluble polymer that has broad range of application and readily synthesized from hydrolysis of N-vinyl formamide(NVF) but hard to control due to its unconjugated monomer structure. Reversible addition fragmentation chain transfer(RAFT) polymerization via rapid equilibrium of chain transfer agent(CTA) afforded the possibility to synthesize controlled poly(N-vinyl formamide)(PNVF) and its block copolymer. In this study, we synthesized a series of poly(vinyl alcohol-b-N-vinyl amine) (PVA-b-PVAm) by RAFT copolymerization of vinyl acetate(VAc) and NVF following by hydrolysis reaction. The conversion and molecular weight calculated by GC and GPC. The chemical structures analyzed with 1H-NMR and FT-IR. The linear first order kinetic plot of ln([M¬0]/[M]) over time and induction period in the initial stage of polymerization were observed, indicating well defined PVAc-b-PNVF block copolymer. |
