LOW-TEMPERATURE PYROLYSIS OF BINARY-MIXTU RES OF HEXACHLOROCYCLOPENTADIENE WITH POLYETHYLENE AND ETHYLENE COPOLYMERS

This study deals with pyrolysis of the binary mixtures of hexachlorocy clopentadiene with polyethylene and various ethylene copolymers. The p rocesses of dehydrochlorination and carbonization, which involve up to five chlorines of hexachlorocyclopentadiene, proceed intensively unde r relatively mild conditions. Using IR spectroscopy, gas chromatograph y, thermogravimetry, and alkalimetric titration, it was shown that HCl and carbonized products are formed in reactions both of hexachlorocyc lopentadiene and intermediate products of its interaction with the pol ymers.
