The influences of concentration of initiator, reaction temperature, concentation of monomer and reaction time on the graft rate, the graft efficiency and the monomer conversion rate of starch polyacrylamide graft copolymer were studied by orthogonal trials, and the corresponding optimum conditions were investigated firstly. Then the synthesized starch polyacrylamide graft copolymer was used to treat waste water from the bleaching workshop of one papermaking mill. Finally the first pass retention of furnish to make paper packaging material and the influences of starch polyacrylamide graft copolymer on the mechanical properties of paper packaging material were investigated. It shows that the first pass retention of furnish to make paper packaging material with the increase of dosage of starch polyacrylamide graft copolymer. With the increase of dosage of starch polyacrylamide graft copolymer, the tensile strength, the breaking length of paper packaging material increase, but the tear strength and the folding endurance decrease.
