MODIFICATION OF CHITOSAN BY GRAFT COPOLYMERIZATION WITH ACRYLONITRILE
Abstract
The graft copolymerization of acrylonitrile onto chitosan with dinitrilazoisobutyric acid as initiator was investigated. The grafted copolymerization was confirmed by infrared spectroscopy. The dependence of the properties of the grafted copolymer on the conformational characteristics of the polysaccharide was established. The degree and efficiency of acrylonitrile grafting on chitosan in the case of the tangle macromolecule conformation are lower than when the macromolecules of the polysaccharide are in the rigid rod conformation under the same synthesis conditions. The grafted copolymers have higher physical and mechanical characteristics compared to the original chitosan.
