Abstract
This paper summarises the investigations of chemiluminescence (CL) measurements as a tool to assess the oxidative degradation of polyolefins. Different CL-measurements techniques are described and evaluated. Furthermore, CL-measurement parameters are described, as well as features, problems and implications of the CL-method. The correlation of integrated CL-emission to peroxide concentration in thermally aged polypropylene (PP) has been investigated with special emphasis. Finally, the importance of CL in relation to another luminescent phenomenon, thermoluminescence (TL), has been studied for polyethylene (PE) after ionising irradiation.
