AB - CHANGE IN MACROMOLECULE STRUCTURE DURING THE HYDROLYSIS OF CELLULOSE TRXACETATE N. A. Fedyakova and L. S. Gembltskii UDC 547.458.82:542.951.92 At present there is no single point of view on the question of conformatlonal change in the unit during the process of cellulose triacetate (CTA) hydrolysis. Information is lacking about a possible change in the steric disposition of side groups in the chain conformation on replacement of the acetate groups by hydroxyl groups. Thus, some Japanese workers [i], on the basis of x-ray structural analysis and IR spec- troscopy, indicate a change in the conformation of the glucopyranoside unit during nitration. On the other hand, in [2, 3], on the basis of theoretical calculatlons of the conformations1 state of dlmeric fragments of the trinitrate and of CTA, the conclusion was drawn that there is a large number of steric forms, due to large conformational possibilities of the side groups, which is the reason for conformational polymorphism. At the same time, the authors of [2, 3] consider that the high cooperative nonvalence interactions hinders the formation of stereoregular conformations, and replacement of nitrate groups by acetate groups does not lead to a change in the stability of the CI,IC group conformation.
