壳聚糖和丙烯酰胺接枝共聚及其作为造纸助剂的研究
Study on the Graft Copolymerization of Acrylamide onto Chitosan and the Using of the Copolymer as Papermaking Additive
【摘要】 在通N2 条件下 ,以硝酸铈铵作为引发剂 ,合成了壳聚糖(chitosan) -丙烯酰胺(AM)接枝共聚物 ,用红外光谱、X -射线衍射对产物进行了表征。并将它用作造纸增强、助留剂 ,取得了较好的效果。
【Abstract】 The graft copolymerization of AM onto chitosan was investigated by using ceric amonium nitrate as redox initiator under nitrogen condition.The graft copolymer was characterized by IR;XRD.And the improvement effect of the paper strength and filler retention was researched by using the graft copolymer.
