Abstract

The compatibility of SRI-3 polyisoprene rubber with plasticizing additives based on recycled petrochemical raw materials (DVCH, DVCH with modifying additive (MA) in the amount of 0.5; 1.0; 2.5; 5.0 and 10.0% mas.) in comparison with industrial petroleum oils (PO-6 and I-20). The compatibility of polymer with a plasticizer additive was evaluated by of experimental data using the equilibrium swelling method. As a result, the polimer-plasticizer interaction parameter (Huggins parameter) and the diffusion coefficient of plasticizing components in the polymer volume were determined. Analysis of the experimental data showed that the plasticizer component based on recycled petrochemical raw materials DVCH has better compatibility with the elastomer matrix SRI-3 compared to industrial oils PO-6 and I-20. Was established that the use of modifying additives in the amount of 0.5 and 1.0% mas. leads to an increase in the diffusion coefficient and a decrease in the Huggins parameter in comparison with DVCH in individual form It indicates their better compatibility with rubber SRI-3. Was shown that a further increase in the content of modifying additive (more than 1.0% mas.) in the volume of plasticizing component DVCH is impractical. This leads to a deterioration of the parameters, and, as a result, to a worse compatibility with the elastomer.
