水溶液聚合法制备了不同水解度的聚丙烯酰胺 (HPAM) ,测定 HPAM的1 3 C CPMAS谱 ,并进行了谱的归属 .讨论了 HPAM低场峰面积与水解度的关系以及 HPAM的分子运动
Polyacrylamide (HPAM) with different degree of hydrolysis was prepared by aqueous solution polymerization, and the 1 3 C CPMAS spectra of HPAM were determined and assigned to spectra.The relationship between low peak area of HPAM and degree of hydrolysis and the molecular motion of HPAM
