During research with the help of mathematical modeling methods have been developed elastomer compositions with optimum composition based on rubbers of general purpose containing shredded vulcanizate modified by nitrogen-containing compounds. Today, the trend of development of polymer materials science is to find efficient ways of using materials known by modifying their properties. The priority in the development of a modern economy is the solution of environmental problems; first of all assess the possibility of re-use of waste as a production of rubber products and bump rubber. As a result, it is identified a synergistic effect of influence of conforming modification on the level of rubber strength, parameters of influence of the physical and mechanical factors on the efficiency of the modification are obtained. It is defined an influence of the equipment type for the manufacture of rubber compounds with shredded vulcanizate. It is developed and tested a mathematical model of the modification process automation of shredded vulcanizate, received the practical confirmation of their performance. The urgency of research in this area is the ability to automate the process of modifying shredded vulcanizate and forecasting results of the use of secondary raw materials for high-quality performance of the final product. This allows to virtually avoiding long and resource-intensive process of experimentation and empirical tests. That, in turn, will reduce the cost of time, human and material resources in order to optimize the manufacturing process.
