摘要
表征了超声辐照引发 MMA微乳液聚合产物的结构 ,透射电镜观察结果表明 ,超声辐照引发 MMA微乳液聚合得到的 PMMA乳胶粒平均粒径为 36 .5 nm,粒径分布窄 ;粘度法测试表明得到的 PMMA分子量约为 5百万 ;红外光谱法和核磁共振氢谱法测试结果表明 ,超声辐照引发微乳液聚合得到的
The structure of PMMA obtained by ultrasonic induced microemulsion polymerization of MMA was characterized by TEM, viscometry, FT IR and 1H NMR. The experimental results show that the average diameter of PMMA microlatex is 36.5 nm with narrow distribution, its molecular weight reaches 5 million, and the syndiotactic tacticity of PMMA obtained by ultrasonic induced microemulsion polymerization increases due to the unique feature of ultrasonic induced microemulsion polymerization.
