摘　　要：本文采用黏度法,对壳聚糖的相对分子质量进行研究,运用一点法和外推极限法相结合,准确求得壳聚糖的黏均相对分子质量的范围,同时研究了测试条件对聚合物特性黏度的影响．Through determining inherent viscosity of Chitosan, use methods of a point calculation and extrapolation to the limit together sharply, is it deal with to contrast, try to get the true molecular weight of Chitosan, and The studies on the effect of testing condition on inherent viscosity and the molecular weight of Chitosan has been carried out.

关 键 词：黏度 壳聚糖 一点法 外推极限法
