The rubbers on the basis of butyl rubber possess high heatand ozone resistance, gas impermeability, resistance to aggressive media and swelling in the water, high dielectric properties. However, along with these positive properties, these rubbers possess also negative characteristics – low endurance at multiple stretching. Now there are scientific works devoted to elimination of this lack by application of new rubber mixtures. For ex., it was carried out the sulphur vulcanization of rubber mixture of butyl rubber having ingredient mixture of glycidyl-1-methoxy-1cyclopentanecarboxylate (GMCPC) [1]. The rubbers prepared by vulcanization of this mixture had also this lack. The investigations of other author [2–6] also did not bring tangible positive results. The solution of this problem requires the carrying out of investigations with application of various classes of the compounds with strictly determined structure as an addition. Taking into account above-mentioned one, this paper has been devoted to the preparation of vulcanizate on the basis of butyl rubber by vulcanization of the rubber mixture containing 2-(2-oxy-6-thiadecyl)oxirane (OTDO), sulphur and butyl rubber and also to the study of structure of OTDO.
