Results of the study vulcanization of polydienes were presented. Vulcanization activators role in the formation of the actual curing agents and the formation of the spatial structure of the vulcanizates was considered. It is shown that to be effective requires the use of sulfur-vulcanization of zinc-containing vulcanization activators with a developed surface, capable of uniformly dispersed in a medium rubber. Activating sulfur vulcanization system elastomers as alloys of zinc oxide with fatty acids and their derivatives, modified halogenated compounds have been developed. Experimental vulcanization activators were tested in formulations of rubber compounds based on styrene butadiene rubber. Found that the use of experienced vulcanization activators enhances the cure rate and improved tensile properties, elastic rubber presumably due to the formation of a network structure of the cross-linking of different nature and energy. It is noted that the use of the experimental products enables products to reduce the vulcanization time by 7-10%. The possibility of reducing the dosage formulation activators in rubber vulcanization by using effective activating systems. The possibility to reduce 4-5 times the content of environmentally dangerous zinc oxide in rubber products and im-proved manufacturing techniques of rubber compounds by the use of experimental products in non-dusting form.
