SPECTROSCOPIC RESEARCH OF POLYIZOBUTYLENE DESTROYED BY DESTRUCTION

Abstract

The temperature dependence of specific heat of poly(isobutene) degraded under the action of strong Lewis acids has been investigated. From the calculated thermodynamic parameters have been drawn conclusions on the structural conversions of the macromolecules in the process of catalytic degradation. By means of 13C NMR the formation of branched macro- molecules was shown. On the basis of the results a degradation mechanism for poly (isobutene) is suggested.
