The oxidation of polypropylene (PP) was performed in a 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 -130Β°C. The oxidized PP was found to contain
Atactic polypropylene was oxidized in solution in the presence and absence of radical initiator over the temperature range of 140' to 200'C under oxygen pressure of 3.3 to 12.4 kg/cm2, and the effects of metal catalyst and additives on the rate, products, and change in molecular weight distribution
## Abstract Thermal oxidation of isotactic polypropylene (PP) at 220 and 280Β°C in air was studied. Gas chromatographyβmass spectrometric analysis was used to separate and identify the volatile products of PP oxidation. Twentyβthree products were identified and 15 substances were quantified. The ald
