Three methods of measuring thermal oxidative stability of polypropylene have been compared. The oxygen absorption and the sealed tube tests give comparable results. The polymer lifetimes in circulating oven-aging tests ditrer significantly from those obtained by the first two methods. The oven-aging

The ultimate properties of thermally oxidized polypropylene (PP) films have been determined. Attention was focused on the variation of draw stress, tensile strength, draw ratio, breaking extension, breaking factor, work of draw, and work of rupture, with a change in temperature and time of heat trea
