The crystal structure, IR absorption, and photoluminescence spectra of isotactic polypropylene composites with multi-walled carbon nanotubes (MWCNT) have been studied. MWCNT concentrations in the range from 0.1 to 5 wt. % are investigated. The influence on the structure and the destruction of the composites during electron irradiation (Eₑ - 1.8MeV) at the absorption doses between 3.0 and 4.0 MGy has been examined. It has been shown that the sensitization with the MWCNT contributes to the crystallization of the composites and causes changes in the molecular interaction. The irradiation influences in a complex manner the composite structuring and degradation processes that depend on the MWCNT content and radiation dose.
