Preparation of chitosan derivative with polyethylene glycol side chains for porous structure without specific processing technique.
The graft copolymer, chitosan-g-polyethylene glycol (PEG), was prepared through graft polymerization of PEG chains to chitosan due to the esterification reaction between PEG and 6-O-succinate-N-phthaloyl-chitosan (PHCSSA). The graft copolymer with porous structure was observed from scanning electron micrographs. It is a potential method to combine chitosan with the hydrophilic synthetic polymers. The graft reaction was carried out in homogeneous system and yielded copolymers with high grafting content. FTIR, NMR, XRD, DSC, spectrofluorophotometer and SEM were detected to characterize the copolymer.
