反相乳液共聚淀粉-丙烯酰胺－丙烯酰氧乙基三甲基氯化铵的合成及应用

In this article, a co-polymer of starch, acrylamide （AM） and acryloyloxyethyl trimethyl ammonium chloride （DAC） has been prepared in a inverse emulsion system using sodium sulphite anhydrous and ammonium persulfate as initiator. The paper discussed the effect of the kinds of emulsifier ,the concentration of initiator, the reaction temperature ,the reaction time on graft copolymerization reaction. The optimal conditions were found as follows: OP-10 and Span-80 as emulsifier , concentration of initiator 0.15%, reaction temperature 35 ℃ and reaction time 5 h. Under these conditions, the intrinsic viscosity was 465 mL/g. The product was measured by IR to identify the construction of graft copolymer. The synthesized copolymer showed excellent properties in the waste water of life treatment .
