| 摘 要： | 简单介绍了Llorens提出的关于从聚合物熔体的流变数据预测多分散指数Mz-Mw的方法，并用Llorens的方法计算了纤维素的多分散指数。将计算的值与GPC测定结果进行对比证明了该法对比较不同纤维素的分散指数具有一定的参考价值。

| Abstract: | This article introduced a method developed by Llorens for determining the polydispersity index Mz/Mw of polymer melt, and the method was used for calculate the polydisperity indices of several kinds of cellulose. The comparison of the results from this method and GPC showed that it is helpful to compare the polydisperity indices of different cellulose by using this method. |
