Four polypropylene powders were prepared under different drying conditions. They were tested with respect to their oxidation induction period (120°C) which ranges between 75 and 347 min. The effect of these differences on processing stability was investigated. Also studied was the oxidation behavior of powder in a fluidized bed (air) in the temperature range 80–140°C.
