摘要
分别采用溶液聚合与反相微乳液聚合制备丙烯酰胺-丙烯酸钠共聚物P(AM/SA),离子色谱法测定聚合物的阴离子度,分别采用F-R法、K-T法和YBR法计算单体竞聚率,通过竞聚率值预测共聚物的微结构,实验结果表明,微乳液聚合比溶液聚合制得的共聚物的结构更趋于无序排列分布.
Copolymerization of acrylamide and sodium acrylate were respectively accomplished in solution and inverse microemulsion. Anion degree was determined by ionic chromatogram. Reactivity ratio was respectively calculated by F - R, K - T and YBR methods. The copolymer microstructure was predicted from the reactivity ratios. Compared to what was obtained for copolymers synthesized in solution, the microemulsion polymerization process yields more homogeneous eopolymers in composition.
