CHEMILUMINESCENCE AND OXIDATION OF POLYPROPYLENE - COMMENTS ON THE HETEROGENEOUS MODEL

It is shown that the recently proposed heterogeneous model for polypropylene oxidation is based on erroneous evaluation of the activation energies and a mistaken interpretation of literature. The fact that the isothermal chemiluminescence data obtained at different temperatures are reducible to a single master curve cannot be considered a proof for the heterogeneous model. Rather, this peculiarity follows directly from the kinetic approach-the very concept the heterogeneous model is intended to discredit.
