Table 1.
Notes:
Moral feed ratio of ɛ-CL to glucosamine units;
Yield (%) = [(WCS-PCL)/(WCL + WCS)] × 100%;
Measured by GPC; polystyrene samples were used as standard;
Average number of ɛ-CL units per glucosamine unit in CS, CLn = A[(a)/2]/A[(3, 4, 5, 6, 6′)/5], calculated from 1H NMR.
Abbreviations: 1H NMR, proton nuclear magnetic resonance; CL, caprolactone; CS, chitosan; CS-PCL, cationic chitosan-graft-poly (ɛ-caprolactone); GPC, gel permeation chromatography; MFR, moral feed ratio; Mw, molecular weight; PDI, polydispersity index.
