【摘要】 采用新型复合引发体系,以Na2CO3为水解剂,研制了高相对分子质量阴离子型聚丙 烯酰胺。结果表明,以Na2CO3为水解剂比以NaOH、NaHCO3为水解剂效果好。在最佳条件下可获 得相对分子质量高于2×107的HPAM。更多还原

【Abstract】 An anionic polyacrylamide with high molecular weight was developed using new compound initiating system in the presence of sodium carbonate as hydrolizing agent. The result shows that sodium carbonate as hydrolyzing agent is much better than sodium hydroxide and sodium bicarbonate. Under optimum conditions, the anionic polyacrylamide with high molecular weight over 2 × 107 was developed.更多还原
