摘要
合成了二甲基二烯丙基氯化铵—丙烯酰胺共聚物 ,测定了水溶性偶氮化合物 -RH引发体系 (PAA·2HCl-RH)和过硫酸钾 -RH引发体系 (KPS -RH)引发共聚反应时单体DM和AM的竞聚率 ,以及PAA·2HCl-RH体系用于DM -AM共聚时的活化能。结果表明 :PAA·2HCl-RH引发DM -AM共聚时 ,DM和AM的竞聚率分别为 0 .174和 6 .8,活化能为 33.2 5kJ/mol;而KPS -RH引发DM -AM共聚时 ,DM和AM的竞聚率分别为 0 .0 76和 7.1。
Dimethyldiallylammonium chloride-acrylamide copolymer is synthesized.The monomer reactivity ratios and apparent activation energy are determined in copolymerization reaction initiated with PAA·2HCl-RH.The results indicate that when DM-AM copolymerization reaction is initiated with PAA·2HCl-RH,the apparent reactivity ratios of DM and AM are 0.174 and 6.8,and activation energy is 33.25 kJ/mol. When DM-AM copolymerization reaction is initiated with KPS-RH,the reactivity ratios of DM and AM are 0.076 and 7.1.
