  • Product Description

Graft polymerization of acrylonitrile onto cellulose fiber initiated by KMnO4/citric acid in aqueous solution was examined and the grafted copolymers were characterized by using NMR, FT-IR, XRD, TG and DSC. Graft yield, GY, obtained by simple weighting method was close to the value obtained by NMR analysis. The most efficient condition was obtained. Also, Graft polymerization of acrylonitrile onto cellulose fiber initiated by KMnO4/different acid in aqueous solution was examined and mechanical properties grafted samples are tested by simple elongation. It was found that the mechanical properties become more poor when strong acids are used, indicating that more chain rupture. After these studies, the grafted cellulose was chemically modified to use in different applied fields. Amidoximated grafted cellulose was obtained by reaction hydroxylamine and cellulose-graft-polyacrylonitrile. The highest value of amidoxime content was 2.42 mmol/g and The adsorption efficiencies of amidoximated grafted cellulose have been evaluated with studying different adsorption conditions. Moreover, Aminated grafted cellulose and its derivatives were prepared with studing thier antimicrobial activities
