A new experimental technique combining highly sensitive heat flow measurements (microcalorimetry) with the simultaneous detection of chemiluminescence intensity was developed. A perfusion ampoule was connected by fibre optics to an external photo-multiplier and photon counter device. The perfusion ampoule was placed in a 201 calorimetric unit used with a 2277 TAM thermostat. The simultaneous approach...
Microcalorimetry (MC) and chemiluminescence (CL) measurements have been used to study the oxidation of unstabilised polypropylene (PP) particles. The oxidation profiles obtained by the two techniques were found to be similar although a time shift between the profiles was observed, particularly at low temperatures. The similar shape suggests a close relation between the rate of the overall oxidation...
