The Effect of Metal-containing Nanofillers on the Properties of Blended and Dynamically Vulcanised Thermoplastic Elastomers Based on Isotactic Polypropylene and Ternary Ethylenepropylenediene Elastomer

New thermoplastic elastomers based on isotactic polypropylene and a ternary ethylenepropylenediene elastomer of different composition (with and without oil) with the use of nanofillers containing nanoparticles of oxides of different metals have been developed. It is shown that a small addition of nanofiller has practically no effect on the crystallinity and dielectric permittivity of the thermoplastic elastomers, but lowers their elastic modulus. The size of the nanoparticles has a considerable effect on the mechanical properties of the materials. The introduction of nanofillers into blends based on oil-extended elastomer does not affect their properties.
