摘　　要：以偶氮二异丁基脒盐酸盐(V-50)为引发剂,丙烯酰氧乙基二甲基苄基氯化铵(DMBC)为聚合单体,采用自由基水溶液聚合法,在氮气氛围中制备了阳离子型聚丙烯酰氧乙基二甲基苄基氯化铵(PDMBC)。用单因素法考察了单体质量分数、引发剂用量、反应温度以及反应体系pH对聚合物黏度和相对分子质量的影响。对反应条件进行了优化,当反应温度为42℃时,可以合成出相对分子质量100万以上的聚丙烯酰氧乙基二甲基苄基氯化铵。The cationic polyacryloxyethyl dimethyl benzyl ammonium chloride(PDMBC)was prepared in nitrogen atmosphere by free radical aqueous solution polymerization method using 2,2'-azobis(2-methylpropionamide)dihydrochloride(V-50)as the initiator,and acryloxyethyl dimethyl benzyl ammonium chloride(DMBC)as the polymerization monomer.The effects of monomer mass fraction,initiator dosage,reaction temperature and pH value on polymer viscosity and molecular weight were investigated by single-factor method.The reaction conditions were optimized,and when the reaction temperature was 42℃,more than 1 million molecular weight of polyacryloxyethyl dimethyl benzyl ammonium chloride can be synthesized.
