常压等离子体引发丙烯酰胺聚合研究

Study of polymerization of acrylamide initiated by atmospheric pressure plasma

利用Ar冷弧等离子体对丙烯酰胺单体进行处理并引发聚合,制备出高吸水性聚丙烯酰胺.研究了放电时间、聚合温度、单体质量分数等对聚合产物吸水性能的影响,实验结果表明在放电时间为90 s,聚合温度为30℃,单体质量分数为30%,后聚合时间为24 h的聚合条件下聚合物的吸水率为340(g/g).

In this study,super absorbent polyacrylamide was prepared by the cold arc Ar plasma which initiated polymerization of Acrylamide.The effects of the discharge time,the polymerization temperature and the monomer concentration on the absorption of the polymer were studied.Result showed that the absorption of the polymer is 340（g/g） under the conditions of the 90 s discharge time,the 30 ℃ polymerization temperature,the 30% monomer concentration and the 24 h polymerization time.
