Abstract
Polymer mixtures based on recycled polypropylene with the addition of an ethylene–octene copolymer underwent extrusion processing to improve its physical and mechanical properties. Experimental thermodynamic and structural parameters of the composite material and its physical and mechanical properties were obtained. An increase in relative elongation at break of the composite materials prepared with an extrusion method as strands and films is due to the plasticization of recycled polypropylene with an ethylene–octene copolymer and a decrease in degree of crystallinity in the range of compositions studied. The possibility of practical use of recycled polypropylene as a part of composite materials for light industry and long products (pipes and film packaging) is shown.
