Decay constants of peroxy radicals from polypropylene and polypropylene model compounds: A kinetic ESR study
The rate constants and the activation energy for the mutual recombination of peroxy radicals generated from atactic polypropylene (PP) and for model compounds of PP and PP autoxidation products have been determined by kinetic ESR. The type of peroxy radicals and the preferred sites of attack for the hydrogen abstraction by t-butoxyl radicals were identified. The results are of interest in respect to the mechanism and the kinetic simulation of PP autoxidation.
