چکیده
The optical and surface-energy properties of polyethylene (PE) subjected to γ-irradiation post-radiation, high temperature, shear grinding are presented. Comparison the IR spectra initial γ-irradiated PE shows that oxygen-containing groups unsaturated bonds in polymer macromolecules formed accumulate during their radiolysis air, increasing with dose. A redistribution products radiation-chemical conversion on surface granules throughout entire volume powder occurs after high-temperature milling a as observed spectrum. Polar functional due oxidation reactions layer sample post-radiation grinding. is weakly basic an acidity parameter −0.34. value made ground irradiated has acidic 0.65. γ irradiation secondary processing waste promising approach obtain specified parameters different degrees functionalization.
