Özet
In this study, different composites were prepared from oxidized polyolefin (OxPO) and synthetic waste (recycled polyolefin) to enhance the mechanical and thermal properties of recycled polyolefin, and the results of experimental studies on the mechanical (elongation, elasticity, tensile strength, etc.) and thermal properties of these composites were discussed. The composites were prepared in a laboratory-scale twin-screw extruder by grafting an oxidized polyolefin/styrene (St) blend onto recycled polypropylene (rPP) using the melt-free radical polymerization method. The prepared composites' mechanical properties (elongation and tensile strength) were determined according to the ISO 527-2 standard method. It was observed that the modulus of elasticity of (OxPO/St/rPP) composites increased by 24% compared to the modulus of elasticity of rPP and the tensile strength increased by 45% compared to the tensile strength of rPP. The composites were characterized by Thermogravimetric analysis and Fourier Transform Infrared (FTIR) spectroscopy. Thermogravimetric analysis (TGA) results showed that the thermal stability of the composites 36 °C increased compared to the thermal stability of rPP. Melt Flow Index (MFI) tests showed a 15% decrease in the Melt Flow Index value of the composites.
