The impact of electron irradiation on the structure of the PA6 polymer is researched in this article. The electron beam irradiation of samples from PA6 was carried out on an industrial pulse accelerator ILU-10 under different modes. Beam energy and radiation dose varied. The structural changes of PA6 were studied by scanning electron microscopy, X-ray phase analysis, IR Fourier spectroscopy, and the thermal characteristics of the polymer were studied by differential scanning calorimetry. It was revealed that after electron beam treatment, the melting temperature of the PA6 polymer decreases from 214 °C to 217 °C. It was found that electron beam treatment leads to a change in the surface morphology, that is, the surface becomes rough, the depth of the roughness and the structure of spherulites increase.
