| Abstract: | The graft copolymerization of acrylamide onto konjac glucomannan (KGM)was studied using potassium per-mamgamate as an initiator. The effects of initiator concentration and comonomer concentration and H2SO4 concentration and reaction temperature and reaction time, as well as preoxidation time on the graft copolymerization were investigated. The results showed that graft efficiency of the graft copolymerization was above 90% under the optium conditions. Meanwhile, both water solubility and thickening properties of the graft copolymers were improved greatly. |
