| Abstract: | The graft copolymerization of acrylamide onto konjac glucomannan(KGM) was studied using potassium permamgamate/thiourea redox systems as an initiator. The effects of concentration of initiator, comonomer and H 2SO 4 and reaction temperature and time, as well as the methods of pretreatment of KGM on the graft copolymerization were investigated. The water solubility and thickening proporties of the graft copolymers and the mechanism of the graft copolymerization were also disscussed. |
