AB - The paper presents the results of the development and study of the structural features and properties of nanocomposites and nanohybrids based on a block copolymer of ethylene with propylene and nanoparticles of the natural mineral clinoptilolite dressed with an organosilicon compound — γ-aminopropyltriethoxysilane. To identify the role of the sizing agent in the nature of changes in the physical-mechanical and thermal deformation characteristics of nanohybrids, the influence of filler content on the tensile strength, tensile yield strength, elongation, heat resistance, and melt flow index was studied. It was shown that the use of sizing agents can significantly eliminate the brittle destruction of nanohybrids even at 30.0 wt% clinoptilolite content. At the same time, the fluidity of the melt of samples in highly filled composites was maintained. The use of the thermomechanical research method made it possible to clearly identify a first-order phase transition, including for dressed nanohybrids. A slight increase in the temperature of the first-order phase transition of dressed nanohybrids has been established, which, in all likelihood, can be associated with the formation of interpenetrating networks in the structure. Depending on the content of dressed clinoptilolite and in accordance with the Kolmogorov–Avrami theory, the mechanism and kinetic regularities of crystallization of nanohybrids and nanocomposites were studied. It has been shown that the use of dressed clinoptilolite nanoparticles contributes to the preservation of the disk-shaped growth mechanism of crystalline formations even at 20.0 wt% content in the graft copolymer of a block copolymer of ethylene with propylene with grafted chains of polymethacrylic acid.
