Synthesis and Characterization of β-Cyclodextin-graft-Polyvinylpyrrolidone Copolymer via Xanthate-Mediated RAFT Polymerization |
| 초록 |
The β-cyclodextrin (β-CD) derivative with an average degree of substitution of 4 (4Br-β-CD) was synthesized by treating β-CD with 4 equivalents of 2-bromo-propionyl bromide. It was then reacted with potassium ethyl xanthate to produce β-cyclodextrin xanthate derivative as the chain transfer agent (CTA) in reversible addition-fragmentation chain transfer agent (RAFT). The graft copolymers β-CD-graft-PVP (polyvinylpyrrolidone) with different chain length were prepared. The structures of 4Br-β-CD, CTA and copolymers were characterized with 1H NMR spectra, and their molecular weight distribution of the copolymers were measured by GPC. |
