Using radiothermoluminescence (RTL), the molecular mobility features in the temperature range of 77–300 K were studied for the polypropylene (PP)/ethylene propylene diene elastomer SKEPT-4044 with NiO, Cu2O, and Fe3O4 nanoparticles (NPs) based on ABS-acrylonitrile butadiene or SCS-divinyl styrene matrices. It has been shown that the introduction of nanofillers in PP significantly affects the nature and temperature of γ- and β-relaxation processes, while the region of manifestation of the β process noticeably shifts to the region of low temperatures. Composites with Cu2O NPs have a higher β-transition temperature Tβ than composites with other NPs. It has been found that PP/SKEPT-4044 composites with Cu2O NPs with a dispersion of 11–15 nm and acrylonitrile butadiene thermoplastics have optimal frost resistance compared to other compositions.
