"TAILORED POLYVINYLAMINES BY RAFT POLYMERIZATION"Mathias DestaracLaboratoire SOFTMAT, Université de Toulouse, CNRS UMR 5623Poly(N-vinylamides) are water-soluble polymers known for decades as aqueous formulation additives for diverse applications. Cyclic monomer derivatives such as N-vinylpyrrolidone (VP) and N-vinylcaprolactam (VCL) can be controlled by nearly all Reversible Deactivation Radical Polymerization (RDRP) methodologies. On the other hand, only a few studies reported the successful controlled polymerization of non-cyclic N-vinylamides such as N-vinylformamide (NVF), N-vinylacetamide (NVA) and N-methyl-N-vinylacetamide (NMVA). We report several RAFT methodologies to control the polymerization of non-cyclic N-vinylamides and prepare original polyvinylamine (PVAm)-based double hydrophilic block copolymers (DHBCS). Metal ion-DHBC hybrid polyion complexes (HPICs) and their activity as catalytic nanoreactors are presented.
