Stress–Strain Properties and Structural Characteristics of a Gamma-Irradiated Polymer Composite Material Based on Low-Molecular-Mass Rubbers

The effect of γ-radiation dose on the mechanical characteristics and structure of a polymer composite material based on PDI-3B and SKD-KTR low-molecular-mass rubbers and filled with potassium chloride has been studied. It has been shown that an increase in the radiation dose to 200 kGy does not lead to a significant change in ultimate tensile stress and strain. The radiation resistance of the synthesized polymer composite materials is also evidenced by the absence of significant changes in the structure of the irradiated composite.
