摘要
采用氧化-还原引发体系,以丙烯酰胺、丙烯酸为单体,通过水溶液聚合合成了高分子量的阴离子型聚丙烯酰胺。研究了EDTA用量、反应时间、pH值和AA/AM配比等对聚丙烯酰胺分子量、聚合转化率以及溶解性能的影响。
Anionic polyacrylamide with higher molecular weight was synthesized by aqueous solution polymerization,with acrylamide and acrylic acid as the monomers.The influences of the amount of EDTA,pH value,reaction time and AA/AM ratio to the polyacrylamide molecular weight,the conversion of monomer and dissolution ability have been studied.
