Notes:
The action of acetyl chloride on the fine structure of regenerated cellulose (fiber and film) has been studied by infrared and x-ray techniques. The two techniques reveal different aspects of the fine structure and are therefore complementary. The changes found on acetylation appear to show that the molecular network theory is inadequate to describe the fine structure of the samples of regenerated cellulose studied. The observed effects can be explained more satisfactorily in terms of a structure in which highly oriented crystallites are interspersed with regions that are highly oriented but not as well ordered, resulting in a variation in density across the cross section.
