摘要
以淀粉、丙烯酰胺 (AM)、二甲基二烯丙基氯化铵 (DMDAAC)为原料 ,采用Fe2 + H2 O2 氧化还原引发体系 ,制备了一系列接枝共聚物 .同时进行了絮凝效果的考察 ,研究了接枝共聚物结构、单体质量比与絮凝性能的关系 ,探讨了絮凝作用的机理 ,并与DMDAAC和AM的均聚物进行了比较 。
Using Fe 2+ H 2O 2 initiation system, a series of graft copolymer were synthesized by copolymerization of starch with acrylamine (AM) and diallyl dimethyl ammonium chloride(DMDAAC). Furthermore the author investigated the flocculation effects, The relationships between the flocculation properties and the chemical composition as well as the amount added of the grafted copolymers was also discussed and was compared with PDMDAAC and PAM. The results show that grafted copolymer flocculation effects are better than PDMDAAC and PAM when the mass ratio of St/(DMDAAC+AM)is respectively 1/3,1/2 5 and 1/2, and the mass ratio of DMDAAC/AM is 2/8.
