New poly(vinyl alcohol)-graft-poly(ethylene glycol) (PVA-g-PEG) resins with various PEG chain lengths, which have high loadings and good swelling both in water and organic solvents, have been prepared via an anionic polymerization of ethylene oxide onto PVA beads and applied in solid-phase synthesis, supported TEMPO catalysis and in HR-MAS 1H NMR spectral analysis.
新型的具有各种PEG链长的聚(乙烯醇)接枝聚(乙二醇)(PVA-g-PEG)树脂是通过阴离子聚合法制备的,该树脂在水和有机溶剂中具有高负载量和良好的溶胀性。将环氧乙烷放在PVA珠粒上,并用于固相合成,支持的TEMPO催化和HR-MAS 1H NMR光谱分析。
