• Mechanical and structural characteristics of gamma-irradiated ABS plastic based on a high-molecular-weight technical acrylonitrile–butadiene–styrene polymer have been studied. The structure and mechanical characteristics of the ABS plastic, both pristine and irradiated with gamma-rays in air at doses of 50, 100, 150, and 200 kGy, have been evaluated. It has been shown that the gamma-radiation post-treatment leads to a change in the structure and mechanical characteristics of the material. In the case of irradiation with a dose of 50 kGy, a sharp increase in strength up to 26.5 MPa is observed with respect to the initial sample, the strength of which is 16.5 MPa, while the strain also almost doubles. At a dose of 100 kGy, the stress and strain somewhat decrease, and this trend persists at radiation doses of 150 and 200 kGy. Based on the results of IR spectroscopy, it was assumed that gamma-irradiation leads to a change in the structure of the plastic; an absorption peak is observed at 3400 cm −1 , being absent for the unirradiated sample, the intensity of which increases with increasing radiation dose. The results of the study are proposed to be used for radiation-stimulated enhancement of the strength and plasticity of ABS plastics.
