Oxidation of Polypropylene in a Solution of Monochlorobenzene

摘要

The oxidation of polypropylene (PP) was solution of monochlorobenzene using tetrabutyl ammonium permanganate either in the presence or absence of purified air and dodecanol-1.The experiments were conducted under atmospheric pressure at 128-130 deg C.The oxidized PP was found to contain polar groups such as carboxylates,carboxylic acids,ketones,esters,ete.as determined by Fourier transform infrared,ultraviolet,nuclear magnetic resonance,and electron spectroscopy for chemical analysis.The presence of the MnO_2 formed upon the decomposition of tetrabutyl ammonium permanganate was determined by electron spectroscopy for chemical analysis.The dodecanol-1 was used as an accelerator for the oxidation reaction of PP in presence of air.Solubility trials of oxidized PP in toluene and methyl ethyl ketone were performed.A reaction mechanism is proposed.
