Physico-chemical approach of polymer chemical ageing: a short review
Article dans une revue avec comité de lecture
Auteur
RICHAUD, EmmanuelRésumé
Polymers are known to degrade in their use conditions, with the risk that their properties reach unacceptable level. This paper reviews the modeling of modifications occurring at molecular and architectural changes occurring during their chemical ageing, with the aim of predicting the physical (mechanical) properties, all values being linked by structure properties relationships
