Abstract (English):
By consideration of kinetic features of thermal degradation of polybutadiene in a gaseous fluid of air, an argon and a carbon dioxide it is erected that increase of temperatures augments velocity of process of the cyclization of rubber, leading to formation of carbon. Indispensable and sufficient stay time of a fragment of rubber in reactionary environment compounds 20 minutes. Recommended temperature range of waste-handling lies within 500-600°С. In a kind of complication of process of thermal degradation of polybutadiene studies of their rubbers are indispensable.
