Poly(vinyl amine) (PVAm), a water-soluble polymer with primary amine groups, is one of the most important functional polymers due to significant modification possibilities. Since it is not possible to prepare the polymer from its monomeric state, several alternative routes to synthesize PVAm were studied. One way to that is using polymerizable N-vinyl monomers as precursor, such as vinyl acetamide and vinyl formamide. 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. The RAFT processes of N-vinyl monomers were carried out by using xanthate type chain transfer agent (CTA). Detailed results will be discussed. |
