摘要
研究了丙烯酰胺与壳聚糖接枝共聚物 (简称 CAM)的制备、结构表征以及对纸张的助留效果的测定 .文中还对接枝共聚物的助留、增强机理进行了探讨 ,结果表明该接枝共聚物加入造纸浆料后可通过对纸料电荷的中和以及接枝共聚物大分子的架桥作用产生很好的絮凝效果 ,同时壳聚糖的多羟基与纤维结合使纸张的干强度也有所增加 。
The synthesis,structure and application of acrylamide(AM) grafted onto chitosan has been studied. It was found that the water solubility and Zeta of graft copolymer (CAM) has been improved. The results of application showed that the grafted chitosan is an effective retention aid and it also can improve the strength of the paper.
