In this work, magnetite nanoparticles are introduced into a polyethylene melt at the stage of a viscous-flow state by standard methods of polymer processing (extrusion), which makes it possible to obtain a nanocomposite with a uniform nanofiller distribution. The phase composition and structure of the nanocomposite were confirmed by XRF, electron microscopy, and IR spectroscopy. It is shown that the preparation of Fe3O4/LLDPE nanocomposites is not complicated by the appearance of unidentified phases and changes in the structure of the polymer matrix.
