The invention is a chemical process for complete destruction and safe disposition of hazardous organic chemicals such as Polychlorinated Biphenyl (PCB). The invention also comprises the process for production of an inert polymer formed of essentially equal parts of Carbon and Sulfur, and also comprises the new inert polymer, itself and articles made of the new polymer.This new polymer has many of the properties of refractory materials and is an inert non-inflammable cross-linked polymer that is relatively insoluble in all generally known solvents. In the process of the invention PCB and Sulfur are heated, in an atmosphere of Nitrogen at 500 to 1500°C. Waste gases including sulfur and sulfides are condensed, scrubbed and the sulfur-recycled. The solids residue when analyzed by a mass spectrometer contains less than one (1) part per million (1ppm) of unreacted polychlorinated biphenyl (PCB).
