| Abstract: | The graft copolymer of starch-acrylamide(AM)-methylacryloyloxyethyl trimethyl ammonium chloride(DMC) was synthesized in aqueous solution by using oxidation-reduction initiation system. The effects of the reaction temperature, reaction time, initiating agent concentration and the mass ratio of monomers on the grafting percentage, the grafting efficiency and the cationic degree were investigated. The optimal reaction conditions were found. The grafting percentage is 136.18%, the grafting efficiency is 79.8%, cationic degree is 19.2% under the conditions of starch 7.5g, acrylamide 15g, initiating agent concentration 0.4mmol/L, reaction temperature 45℃, reaction time 5h, m(DMC):m(AM)=1:3. |
