    Reactivity Ratios of Copolymerization of 4-Vinylpyridine and Acrylamide

      摘要
    • 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。

       

      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 th
