The mechanical properties of a polymer product depend upon its thermal and mechanical history; intrinsic properties are a phenomenological tool to account for this dependence, however a clear link between the molecular structure and processing conditions on one hand, and intrinsic properties on the other, is still missing. The aim of this project is to use experiments and simulations to investigate such a connection, with a particular focus on yield kinetics and the mechanism of physical ageing, which causes polymers to embrittle over time.
