Abstract

[en] Poly(vinylamine) (PVAm) is involved in a broad range of applications due to its interesting properties including complexation of metallic ions and polyelectrolytes, pH responsiveness, adhesion to surfaces, etc. It is currently prepared by hydrolysis of poly(N-vinylamide)s synthesized by conventional radical polymerization. Although controlling the molecular parameters of PVAm could be useful to finely adjust its properties, it remains challenging. In this work, we developed the controlled homopolymerization of N-vinylacetamide (NVA) via organometallic-mediated radical polymerization (OMRP) in the presence of cobalt complexes. The controlled copolymerization of NVA and vinyl acetate (VAc) was then studied leading to unique well-defined statistical copolymers. In order to have a precise idea of the structure of these copolymers, we determined the comonomers reactivity ratios. The synthesis of block copolymers was also explored. Eventually, the hydrolysis of these NVA/VAc-containing copolymers was optimized giving access to unprecedented poly(vinylamine) and poly(vinylalcohol)-based copolymers.
