Abstract
Oxidation of polypropyleneketone by molecular oxygen in the range 80-190 de grees C has been investigated. The rate of oxygen consumption decreases wit h increasing temperature in the range 140-150 degrees C. Reaction involves mainly the zones of short-range order violation comprising about 11% of the polymer. Mechanisms of the phenomena are discussed. (C) 1999 Elsevier Scie nce Ltd. All rights reserved.
