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.
通过将环氧乙烷在聚乙烯醇（PVA）珠粒上进行阴离子聚合反应，制备了具有不同聚乙二醇（PEG）链长度的新型聚乙烯醇接枝聚乙二醇（PVA-g-PEG）树脂，这些树脂在水和有机溶剂中都具有高负载量和良好的溶胀性，并应用于固相合成、负载型TEMPO催化以及高分辨魔角旋转1H NMR光谱分析。
