壳聚糖-丙烯酰胺接枝共聚物用作造纸增强、助留剂的研究

Study on the Technological Parameter by Graft Copolymer of Chitosan and Acrylamide as Paper Strengthening and Filler Retention Agent

本文采用正交实验方法研究了不同工艺条件下壳聚糖－丙烯酰胺接枝共聚物（ＣＡＭ）用在麦草、针叶木混合浆料中时所起到的增强、助留效果，获得了最佳使用工艺条件；并对不同分子量的壳聚糖所合成的助剂的使用情况进行了研究。

Using cross experimental design method, the improvement effect of the paper strength and filler retention was researched by using the graft copolymer of chitosan and acrylamide under different technological parameter. And the optimum technological parameter was acquired. The improvement effect was also researched by adding copolymer which was produced by different molecular weight chitosan and acrylamide.
