Abstract
Intermediate and final cyclic structures, formed during the reaction o f alkaline hydrolysis of poly(acrylonitrile) macromolecules in dilute solutions, were identified by methods of optical spectroscopy. The pos sibility to use these techniques is based on retardation of the kineti cs of elementary reactions within a compacted polymer coil under the a ction of alkali. Variation of the electrochemical parameters of soluti ons allowed the absorption bands of intermediate structures in the spe ctra to be resolved. A scheme of structural transformations in heteroc ycles is given.
