The influence of the nature of polyvinylpyrrolidone silicate fillers on the structure and properties of polyamide-6 has been established. It has been found that the introduction of polyvinylpyrrolidone silicate filler into polyamide leads to a significant increase in the degree of its crystallinity, while a change in the size of crystallites is also observed. The introduction of a filler based on co-precipitated sodium liquid glass and polyvinylpyrrolidone into polyamide-6 reduces the value of volumetric technological shrinkage and equilibrium water absorption. The change in the structure of polyamide under the influence of the filler and its modifier also affects the value of the surface hardness of composites and the Vicat softening point.
