Investigation and Improvement of Thermal and Mechanical Properties of Recycled Polypropylene / Oxidized Polyethylene Composites

Abstract

In this study, various composites were prepared from synthetic wastes with oxidized polyolefin (OxPO) and the mechanical (elongation, elasticity, tensile strength, etc.) of these composites.) and discusses the results of an experimental study on its thermal characterization. The oxidized polyolefin/Styrene (St) mixture was infused with the melt free radical polymerization method on recycled polypropylene (rPP). The effect of the initial monomer concentration on the mechanical properties of recycled polypropylene was investigated. The mechanical (elongation and tensile strength) properties of the composites produced were made according to the ISO 527-2 standard method. It has been observed that the tensile strength and elongation, which are the mechanical properties of (OxPO/St)/rPP composites, increase compared to RPP. The resulting polymers were then characterized by Fourier transformational infrared spectroscopy (FTIR).
