摘    要:测定了丙烯酰胺与4-乙烯基吡啶共聚反应的竞聚率。用紫外分光光度法测定了不同浓度的4-乙烯基吡啶均聚物的吸光度,从而求出在低转化率不同初始单体组成的共聚物中4-乙烯基吡啶含量。用FR和KT两种作图法及YBR计算法对单体的竞聚率进行计算和比较。结果表明:KT法和YBR法计算法较为准确,4-乙烯基吡啶的竞聚率和丙烯酰胺的竞聚率分别为γrVP=0.636,γAM=0.379。

关 键 词:丙烯酰胺  4-乙烯基吡啶  共聚合  竞聚率  水处理剂  水处理工业

Abstract:The reactivity ratios of copolymerization of 4 vinylpyridine and acrylamide were detetmined. The absorbency of various concentration poly(4 vinyl pyridine) could be determined by ultraviolet spectrophotometry, the working curve could be built and the content of copolymer of various initial monomer composition could be measured. Monomer reactivity ratios were calculated and compared using both FR and KT methods. The results showed that the reactivity ratios determined using KT constructing method and YBR calculating method are more accurate, and the monomer reactivity ratios of 4VP and AM were r 4VP =0.636, r AM =0.379.
Keywords:acrylamide  4  vinyl pyridine  copolymerization  reactivity ratio
