二醋酸纤维素-聚乙二醇接枝共聚物的核磁共振表征
NMR Characterization of Graft Copolymer of Cellulose Diacetate with Polyethylene Glycol
【摘要】 用1HNMR和 13CNMR核磁共振技术研究了二醋酸纤维素和聚乙二醇的接枝反应 ,并确定了 1HNMR和13CNMR谱中各谱峰的归属 ,为证明二醋酸纤维素和聚乙二醇的接枝反应提供了依据
【Abstract】 The grafting reaction between cellulose diacetate and polyethylene glycol was studied by 1H NMR and 13C NMR. 1H NMR and 13C NMR spectra of graft copolymer of cellulose diacetate with polyethylene glycol (CDA _ g _ PEG) were assigned completely. The results provide basis for confirmation of grafting reaction between cellulose diacetate and polyethylene glycol.
