Poly(vinyl amine) (PVAm), a water-soluble polymer with primary amine groups, is one of the most important functional polymers due to its significant modification possibilities and polycationic nature. Since PVAm cannot be prepared from its monomeric state, N-vinyl monomers, such as vinyl formamide (NVF) and vinyl acetamide (NVA), has been used to prepare precursor polymers that can be transformed to PVAm by the subsequent hydrolysis of the amide group. However, there have been few studies about reversible deactivation radical polymerizations of nonconjugated N-vinyl monomers. This comes from the fact that the generated radical species are highly reactive because of the lack of resonance stabilization and strong electron donating pendant groups. In this study, we synthesized PVAm through reversible addition-fragmentation chain transfer (RAFT) polymerization of N-vinyl monomers. Furthermore, PVAm based block copolymers were synthesized as a pH responsive materials in aqueous solution. |
