According to the data of X-ray phase diffraction analysis and differential scanning calorimetry, it is shown that the materials based on polycaprolactam (PL-6) and foamed polystyrene (FPS) modified with polyvinylpyrrolidone (PVP) have a degree of crystallinity higher than for PL-6 by 10–15% and a lower mean size of crystallites due to the higher compatibility of the components and the presence of additional crystallization centers. It is shown that the addition of FPS modified with PVP promotes an increase in the yield limit and ultimate tensile strength of PL-6. We discovered an increase in the Vicat softening point and in the surface hardness caused by the redistribution of intermolecular bonds between the components of the mixture under the influence of PVP uniformly distributed in FPS. As a result, the compatibility of the components increases, and the structure of the material becomes more condensed.
