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
Thermoanalytical techniques have been used to investigate the oxidative thermal degradation of polypropylene with special reference to the inhibiting effects of certain metal chelates. The inhibiting efficiency, defined in terms of the difference in temperature between the melting point of the polym
