The effect of the mass ratio of acrylamide (AM) to dimethyl dially ammonium chloride (DMDAAC) on the graft copolymerization of starch and mixtures of DMDAAC and AM was investigated at dose of 3 kGy in aqueous solution. The cationic degrees of grated products is 24.3%, 19.4% and 23.1% with 0.25, 1.5 and 1.86(,W,AM,: ,W,DM,), respectively. And the graft efficiency of DMDAAC onto starch increases with the increment of the amount of AM in mixtures and the maximum value occurs at ,W,AM,: ,W,DM,=1.86. The total graft yield, the total graft efficiency, the monomer conversion rate and the production rate increase with the amount of AM in mixtures.
