摘　　要：采用3种不同的活化方法活化竹纤维素,再进行溶解,对所得溶液进行凝胶渗透色谱法(GPC)测定,确定了甲醇/DMAc置换法是所采用的3种活化方法中较佳的活化方法,并研究了竹纤维素在LiCl/DMAc体系中的分子量大小和分布的特点。In this paper three ways are adopted to activate and dissolve bamboo cellulose, and then the solutions obtained are tested by GPC. The methanol/ DMAc exchange is considered better than the other two ways adopted to dissolve the bamboo cellulose, the characteristics of the molecular mass and distribution of different bamboo cellulose in LiCl/DMAc system are also studied.
