Features of Thermal Oxidation of Polyacylonitrile in the Presence of Carbon Nanotubes

Chemical transformations in the course of heat treatment of polyacrylonitrile films containing highly dispersed multiwalled carbon nanotubes have been analyzed. It has been shown that the introduction of the nanotubes results in the cyclization reaction completeness at lower temperature in comparison of the pristine polyacrylonitrile, and the formed product has more regular structure.
