ABSTRACT:
The present invention is to provide a technology to establish a new cycle-based organic chemical industry, which may be called a polymer cascade (polymer reflux industry) wherein the polymer substances shall not remain the final products, but still give birth to synthetic materials as raw materials for chemical industry and produce useful organic compounds.The present invention to destroy polymer substances by severing a part of molecular chains from the said polymer substances by means of allowing nitrogen dioxide and/or dinitrogen tetraoxide to do oxidative decomposition reaction in inert gas, or destroying polymer substances by severing a part or all of molecular chains from the said polymer substances by allowing nitrogen dioxide and/or dinitrogen tetraoxide to do oxidative decomposition reaction in supercritical carbon dioxide, or to treat polymer substances that are at least one of what are selected from polymer substances of addition polymerization type, polyaddition type, polycondensation type or addition condensation type, or waste polymers thereof, or petroleum fraction of high boiling point.
