ESTIMATION OF RATE CONSTANTS DURING POLYPROPYLENE AUTOXIDATION.

Abstract

Recently the rate constants for the autoxidation of isotactic polypropylene based upon a postulated relatively simple scheme were calculated. Electron spin resonance, volumetric and chemical techniques were employed. This paper demonstrates that similar values of these rate constants could also be calculated from a more general scheme. From this general scheme, expressions were derived which involved the rate constants of interest and other constants which had been previously calculated from experimental data based upon the use of infrared absorption techniques. The values of the calculated rate constants at various temperatures agreed well with those reported earlier where comparison was possible. (Author)
