摘　　要： 壳聚糖用作纸张干增强剂已有较多的报道,但其粘度和脱乙酰度的大小对纸张增强效果影响的研究尚属空白。本文以漂白针叶木硫酸盐浆为原料,对较宽粘度范围和脱乙酰度范围的壳聚糖样品进行了筛选。以对木浆的增强效果为标准,从中选出了几种增强效果较好的样品,为壳聚糖的进一步改性奠定了基础。 It is usually reported that chitosan is used as paper strengthening agent. However, it is vacancy that the study of the different DD（degree of de-acetyl ）and viscosity of chitosan on the effect for paper strength. Many chitosan of wide viscosity range and wide DD range were tested by their strengthening effect on NBKP. Then a few sample of chitosan is selected because of their obvious strengthening effect on wood pulp. This study is base of more research of chitosan used as paper strengthening agent.
