Abstract
In order to find new directions for the use of polymeric material of worn rubber products, the hydrosulfidation of crushed rubber of automobile tire treads was carried out by two methods: polysulfidation followed by desulfidation with alkali and interaction with hydrogen sulfide. According to the first variant the content of mercaptogroups reaches 10%, according to the second variant at atmospheric pressure and room temperature up to 0.6%, at overpressure up to 1 atm 1.5%. It is shown that at treatment with hydrogen sulfide both physical absorption and chemisorption take place. The data on influence of temperature on speed of sorption of gaseous hydrogen sulfide are received.
