采用自由基胶束聚合,通过丙烯酰胺与甲基丙烯酸十二烷基酯的反应,制备得到了疏水链段在主链上嵌段分布的疏水改性聚丙烯酰胺(HMPAM),随后采用乌氏粘度计、核磁共振等方法对其分子结构、分子量、疏水取代度以及嵌段疏水基团的平均长度进行了表征和分析。
The free-radical micellar polymerization was used to prepare the hydrophobically modified polyacrylamide (HMPAM) in which the hydrophobic segments were block-distributed in the main chain through the reaction of acrylamide and dodecyl methacrylate. Viscometer and nuclear magnetic resonance were used to characterize and analyze the molecular structure, molecular weight, degree of hydrophobic substitution and the average length of block hydrophobic groups.
