以甲胺、烯丙基氯、NaOH、氯化苄和偶氮二异丙基咪唑啉盐酸盐为原料,合成了聚二烯丙基甲基苄基氯化铵(PDAMABC),采用FT-IR、<'1>H NMR和元素分析对其结构进行表征,并考察了其在氯化钠、氯化钾、溴化钾、氯化钙、氯化镁、硫酸镁和硫酸钠溶液中的粘度行为.将所得水相和低沸点馏分回用,二烯丙基甲基胺的收率从72.79%提高至83.41%;以水与乙醇为混合溶剂(V(HCO):V(C<,2>H<,5>OH)为1:3～2:3),合成的二烯丙基甲基苄基氯化铵收率较高且水溶性好.PDAMABC的比浓粘度随外加盐浓度增加而降低.在0.1 mol/LNaCl溶液中,当其质量浓度低于0.031 25 g/L时,表现为聚电解质行为;质量浓度大于0.125 g/L时,表现为中性聚合物的牯度行为.外加盐对比浓粘度的影响顺序为:Na<,2>SO<,4>
