二醋酸纤维素接枝聚己内酯的核磁共振表征

NMR Characterization of Graft Copolymer of Cellulose Diacetate with Polycaprolactone

用1H NMR和13C NMR研究了二醋酸纤维素(CDA)和聚己内酯(PCL)的接枝共聚反应,确定了1H NMR和13C NMR谱中各谱峰的归属,为证明二醋酸纤维素和己内酯的接枝共聚反应提供了依据。

The grafting reaction between cellulose diacetate (CDA) with polycaprolactone (PCL) was studied by ()^()~1H-NMR and ()^(13)C-NMR. ()^()~1H-NMR and ()^(13)C-NMR spectra of copolymer of cellulose diacetate with polycaprolactone (CDA- g -PCL) were assigned completely. The results provide basis for confirmation of grafting copolymerization between cellulose diacetate and caprolactone.
