Utilization of the Wastes of Fibrous and Film Polyethylene and Polypropylene Materials by Means of Surface Oxidation
Physicochemical regularities of the surface oxidation of materials made of polypropylene, polyethylene and their wastes were studied as the method to make secondary polymer materials. The properties of the obtained samples were studied. A comparative analysis of the results of modification of the wastes of fibrous and film materials of polyolefins using different methods (oxidation with atmospheric oxygen in the aqueous medium, in the gas phase, ozonation) shows that the simplest and the most efficient method is non-initiated solid-phase thermal oxidation with atmospheric oxygen.
