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 ...
