Résumé : The drop of the elongation at break of gamma irradiated polypropylene samples has been studied as a function of dose and of time after irradiation. A simple relation is proposed that takes into account two chain scission mechanisms, one occurring during irradiation and the other operative after irradiation. The relation includes two parameters measuring the relative importance of those two mechanisms. It allows the prediction of the life-time of radio-sterilised samples.
