ENSCM, salle de conférences Recherche (Bâtiment Max Mousseron, 4e étage), 8 rue de l’école normale, Montpellier

This talk focuses on the use of RAFT chemistry (Reversible Addition-Fragmentation chain Transfer polymerization) under different conditions. In the first section of the talk I will present how RAFT chemistry was employed to modify cellulose and a novel route to improve and tune the physical properties of cellulose. In a second part, I will present the syntheses of a range of glycopolymeric architectures (linear, branched and hyper branched) by a combination of RAFT and click chemistry. Finally, I will show the synthesis and in situ self-assembly of diblock and triblock functional copolymers; as well as the preparation of core-shell organic/inorganic particles using these self-assembled structures.
