Synthesis and Characterization of Oxidized Polyethylene wax of Arak Petrochemical Complex and Preparation of Nanocomposite Based on Organoclay

Low molecular weight polyethylene (wax) was produced as a byproduct during of polyethylene production by slurry – phase processes in hexane. This compound is soluble in hexane and isolated in separation section. Molecular weight fractionation of wax was performed by heptane as solvent then wax separated samples were oxidized at presence of air by benzoyl peroxide as catalyst at free solvent condition for production of oxidized wax. At finally in this research nanocomposite was prepared by solution technique based on oxidized wax and different concentration oforganoclay.The microstructure of these composites was characterized by SEM and XRD. SEM and XRD confirmed the intercalated structure of nanocomposite and also thermal stability and swelling behaviour of nanocomposite were studied.
