Abstract

Mechanically activated dehydrochlorination of polyvinyl chloride in the presence of lithium, potassium, and calcium hydroxides was studied. Short joint mechanical treatment of polyvinyl chloride with the above bases in a high-energy centrifugal planetary mill for 5–10 min ensures the formation of polymers with a conjugated double bond system (polyvinylenes). Their subsequent heat treatment at temperatures of up to 400°С yields amorphous carbon structures. Activation of the resulting material in a CO2 medium at 850°С results in the formation of a micro-, mesoporous carbon material with the prevalent mesopore volume. The results obtained can serve as a basis for the development of technologically acceptable procedures for polyvinyl chloride waste processing to obtain demanded carbon materials without dioxin formation.
