Nanocomposites PVC–MWCNT with different content of carbon nanotubes (0.2–2.0 wt.%) are synthesized. The structural properties and photoluminescence spectra of nanocomposites obtained in the initial state and after high-energy electron irradiation with absorption dose of 0.05 MGy are studied. As shown, the PVC is partially crystalline polymer with crystallinity, which varies nonmonotonously due to doping and irradiation. Because of dehydrochlorisation of the PVC, in polymer macromolecules, structural defects appear as polyene sequences that results in emission of the PVC. Recombination radiation of nanocomposites with tubes varies due to the transformation of the electronic structure of polyenes, which is caused by the appearance of the donor–acceptor interaction between the nanotubes and the polyenes of PVC macromolecules.
