溶胀态下交联高分子的二维及固体高分辨MAS NMR研究

2D and Solid State MAS NMR Studies on Crosslinked Polymer Gels in Swollen State

以不同交联度的PH敏感丙烯酰胺-丙烯酸P(AmNaAc)及温敏异丙基丙烯酰胺-丙烯酸P(NIPA-Ac)交联共聚水凝胶为实验体系,研究了用二维及固体高分辨NMR技术表征溶胀态下交联高分子材料微观结构的方法,结果表明,高灵敏度的 2D HMQC、NOESY及固体高分辨 MAS NMR技术是研究这类体系微观结构的有力工具。

2D and solid state MAS NMR Studies have been made on pH and temperaturesensitive P(Am-NaAc) and P(NIPA-Ac) polymer gels with different crosslink density in swollen state, the experi-ment results have been shown that the high sensitive 2D HMQC、 NOESY and solid state MAS NMR are powerful tools to study the microstruc-ture of this kind of system.
