Kinetics of graft copolymerization of acrylonitrile onto konjac glucomannan initiated

The studies on ammonium ceric nitrate initiated graft copolymerization of acrylonitrile onto konjac glucomannan (KGM) were reported in the paper.The relationship between grafting rate and initiator concentration, monomer concentration, KGM concentration and reaction temperature and the effection of impact factors on graft copolymerization were studied.Based on the experiment result, the equation for the graft copolymerization was derived and the apparent activation energy was calculated, that was 22.08kJ/mol.
