The influence of the nature of the fillers based on polyvinylpyrrolidone and precipitated sodium liquid glass on the morphology and properties of polypropylene has been established. The modification of polypropylene with polymer-silicate fillers contributes to a change in the morphology of the composites, in particular, an increase in the degree of crystallinity and a decrease in the average size of crystallites are noted. Due to the change in the structure, composites based on PVP-silicate filler and polypropylene have increased tensile strength, Vicat softening point, surface hardness.
