The article deals with the study of the influence of additives of unsaturated rubbers and reactive low-molecular compounds on the structure and properties of modified ethylene propylene rubbers (EPR). Synthesis methods involve the introduction of those components into the vulcanization process in order to improve the key characteristics of polymer materials. The results of the analysis of rheological, thermal, and mechanical properties of modified EPR are presented. During the experiments, it was established that the introduction of unsaturated rubbers and reactive low-molecular compounds leads to significant changes in the structure of the polymer matrix. The resulting composites exhibit improved mechanical properties, including increased strength and elasticity. The rheological analysis revealed changes in the viscoelastic properties of the material, indicating modification of the internal polymer network. The presented results expand the understanding of elastomer modification processes and also highlight the potential of those additives to create polymer materials with optimized properties. The practical significance of the obtained results may shed light on new ways to develop advanced polymer composites with improved performance and durability.
