采用溶剂萃取法对一组ds1.8甲基纤维素进行分馏。所有馏分都研究了它们的单体组成和甲基在聚合物链中的分布。与未分选样品相比，对随机模型的偏差和4个样品之间的差异具有更高的灵敏度和更强的差异性。概述并讨论了纤维素醚在不同层次上的结构复杂性。
A set of methyl celluloses of DS 1.8 has been fractionated by stepwise solvent extraction. All fractions have been investigated with respect to their monomer composition and methyl distribution in the polymer chains. Deviation from the random model and differences between the four samples could be determined with higher sensitivity and more differentiated than for the unfractionated material. Structure complexity of cellulose ethers on different hierarchical levels is outlined and discussed.
