| Abstract: | The graft copolymer chitosan-g-poly(vinyl alcohol), with nontoxicity, biodegradability, and biocompatibility, was prepared by a novel method. The copolymer with porous net structure was observed by scanning electron microscopy (SEM). It is a potential method to combine chitosan with the synthetic polymers. The grafting reactions were conducted with various poly(vinyl alcohol) (PVA)/6-O-succinate-N-phthaloyl-chitosan (PHCSSA) feed ratios to obtain chitosan-g-poly(vinyl alcohol) copolymers with various PVA contents. The chemical structure of the chitosan-g-poly(vinyl alcohol) was characterized by Fourier transform infrared and nuclear magnetic resonance (NMR) spectroscopy. Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and SEM were also detected to characterize the copolymer. |
