| Abstract: | Objective] In order to further develop and use konjac resources,its viscosity and water-solubility was improved.Method]Cerium ammonium nitrate(NH4)2Ce(NO3)6 initiated graft copolymerization of N,N-diethylenediacrylamide onto Konjac glucomannan.The reaction rule and the partial nature of graft copolymer were studied.Result]The best conditions of grafting copolymerization reaction were as follows: N,N-diethylenediacrylamide concentration of 1.5 mol/L,cerium ammonium nitrate concentrations of 8.0 mmol/L,reaction temperature of 60 ℃,reaction time of 2.5 h.Conclusion]Water-solubility and solution viscosity properties of graft copolymer was improved,and the graft copolymer could be used for industrial thickener and starching agent. |
