Le vieillissement thermo-oxydant des polymères est-il modélisable ?

Abstract

It has been supposed, for a long time, that kinetic modelling of polymer ageing for nonempirical lifetime prediction was out of reach for two main reasons: hypercomplexity of mechanisms and heterogeneity of reactions. The arguments relative to both aspects are examined here. It is concluded that, thanks to recent advances, especially the introduction of numerical methods, kinetic modelling is possible in various important practical cases.
