Kohler et al. discussed the potential of the chemiluminescence technique as an industrial test method. Imaging chemiluminescence was used to assess antioxidant performance. An advantage over oven aging was found to be the possibility for evaluation of the oxidative stability of samples with unusual geometries, such as fibres and powder particles [136]. A correlation was also found between oven aging and chemiluminescence measurements on stabilised PP and it was shown that chemiluminescence measurements done at...

This type of information cannot be obtained by DSC or TGA. Figure 2.7 shows the results of these experiments compared with the ones measured by DSC. The plot shows good correlation between these techniques regarding the onset time of the oxidation phenomenon. DSC and chemiluminescence produced reliable and rapid OIT results if the experiments were conducted at temperatures well above the melting point. Thus, the effectiveness of the residual stabilising package can be determined identically by either of these techniques. 

These workers sought correlation between physico-mechanical tests and DSC-chemiluminescence-based techniques using MFI and DSC-chemiluminescence with PP stabilised with different antioxidant systems. Their results suggest a strong correlation between results obtained by the two types of test. There is, however, no correlation between the yellowness index and DSC-chemiluminescence.
