摘　　要：通过凝胶色谱 (GPC)分析 ,得到了木粉聚醚分子量 ,其数均分子量为 2 85 3,重均分子量为 2 6 5 6 ,大于常规聚醚的分子量 ,分散指数为 1.0 8,属于窄分布 .同时 ,借助木粉聚醚的红外光谱谱图 ,对其结构进行分析知 ,木粉聚醚具有和常规聚醚相似的分子结构 ,是一种含有多羟基。In this paper, the molecular weight of wood flour polyether is obtained through GPC analysis that is more than that of regular polyether. The number average molecular weight is 2853 and the weight average molecular weight is 2656. The dispersancy index is 1.08, classfied into narrow distribution. Meanwhile, the molecular structure of wood flour polyether is analyzed through IR spectrograms, and a conclusion is drawn that the structure of wood flour polyether is similar to that of regular polyether and the wood flour polyether is a kind of high polymer with polydydroxyl,glucosidic bond and ether link.
