| Abstract: | Starch(S),diallyl dimethyl ammonium chloride(DMDAAC),acrylamide(AM) as raw materials,using redox initiator system,the graft copolymers S-DMDAAC-AM was synthesized.The effects of reaction temperature,reaction time,initiator concentration,monomer ratio on the graft copolymerization of grafting ratio,grafting efficiency,and flocculation and other factors were investigated.The results showed that optimum conditions for starch(S) ∶ monomer volume=3.5g ∶ 10.5g,reaction temperature 70℃,reaction time 4h,initiator concentration and 0.035g,monomer ratio AM ∶ DMDAAC=7 ∶ 3.Under the condition,the average grafting rate G was 144.26%,the average grafting efficiency GE was 82.65%,the average light transmission rate of sewage treatment was 69.37%. |
