Preparation and investigation of properties of nanocomposite thermoplastic elastomers on the basis of isotactic polypropylene
It has been investigated the inluence of additions of metal-containing nanoillers including nanoparticles of copper oxide stabilized on the various polymer matrices: polyethylene (PE) and acrylonitrile butadiene thermoplast (ABS), on peculiarity of properties of thermoplastic elastomers of mixture and dynamically vulcanized on the basis of isotactic polypropylene (PP) and ethylene propyl diene elastomer (EPDR) by methods of X-ray phase analysis (RFA) and infrared spectroscopy (IRS). It has been shown that non-polar PE-matrix favors creation of ine-crystalline structure of composition, in connection of which its properties are improved; polar ABS-matrix forms permolecular formation heterogeneous on types and sizes, i.e. macromolecules ABS are located as separate domains in matrix PP/EPDR, in connection of which the physical-mechanical properties of composition are deteriorated.
