Résumé

Controlled radical polymerization has recently been used to develop polymers engineered for applications as catalytic nanoreactors. In this contribution, we present the joint development, in our laboratories, of core-cross-linked micelles (CCM) for application under aqueous biphasic conditions through the micellar approach, using triphenylphosphine (TPP) as polymer-anchored ligand and rhodium as catalytic metal for the hydroformylation of 1-octene as a model a-olefin. The polymers were synthesized by a one-pot convergent approach using RAFT as controlling method in water, making use of the polymerization-induced self-assembly (PISA) principle. The article will also show the polymer properties in terms of size, polydispersity, swelling, metal coordination and exchange, and interpenetration. It will also illustrate our initial catalytic studies with focus on the effect of the polymer architecture (ligand nature, ligand density, core size, nature of cross-linking) and of the stirring rate on the catalytic performance (turnover frequency) and catalyst leaching.
