The aim of this project is to develop PU in a sustainable way, through the involvement of a Diels-Alder/retro-Diels-Alder cycle and by combining two approaches :

  • The first one consists in synthesizing PU networks from elastomer wastes such as tires wastes. Functionalizations of tires wastes through metathesis reactions is envisaged in this context;
  • The second aims at designing reversible cross-linked PU networks using the thermally reversible DA reaction, with a particular interest in studying the impact of the nature of the adducts and the influence of the crosslink density on the thermomechanical properties of the networks and their recyclability.
