Preparation and Properties of Metal-Containing Nanocomposites Based on Isotactic Polypropylene and Butadiene–Acrylonitrile Rubber

Abstract

Abstract The effect that nanofillers containing copper oxides stabilized with a maleinized low-density polyethylene matrix and prepared mechanochemically exert on the structure and properties of metal-containing nanocomposites based on isotactic polypropylene and butadiene–acrylonitrile rubber was studied by X-ray diffraction and differential thermal analysis. The filling improves the strength, deformation, and rheological characteristics of the nanocomposites and enhances their resistance to thermal oxidation, which is probably due to the synergistic effect caused by interaction of copper-containing nanoparticles with maleic groups of maleinized low-density polyethylene. The nanocomposites based on isotactic polypropylene and butadiene–acrylonitrile rubber can be processed not only by pressing, but also by pressure casting and extrusion, which expands their application field.
