Chemiluminescence from peroxides in polypropylene: II. Luminescence and kinetics of peroxide decomposition

摘要

The kinetics of the weak chemiluminescence (CL) observed when partially oxidised polypropylene is heated in an inert atmosphere have been studied. CL from isothermal decomposition of peroxides is shown to decay more Rapidly than do the peroxides, following second-order kinetics. Kinetic analysis Allows both the activation energy for peroxide decomposition and the Temperature dependence of the emission quantum efficiency to be determined.
