摘要
采用UV(紫外光)聚合法合成了淀粉丙烯酰胺接枝共聚物(St-PAM)。通过实验研究了UV法合成St-PAM的影响因素和最佳工艺条件;对合成物进行了检测和絮凝效果试验。结果表明,UV法合成淀粉丙烯酰胺接枝共聚物是可行的,其合成物用作絮凝剂时,具有相当于或优于PAM的絮凝效果。
Starch-acrylamide graft copolymer （St-PAM） was synthesized by means of UV （ultraviolet） polymerization. Experiment research was undertaken on the factors influencing the UV polymerization, as well as on the best technical conditions for it. And meanwhile the copolymerization and its flocculation effect have also been checked in experiments. Results show that not only it is feasible for starch - acrylamide graft copolymer to be synthesized with such UV polymerization method, but also the obtained starch- acrylamide graft copolymer has an equivalent or even better flocculation effect than PAM when it is used as flocculent.
