Poly(N-vinylamine) (PVAm) is a promising polymer, having a large amount of primary amine groups, but there are only few reports regarding the controlled radical polymerization of N-vinylamine monomer. We synthesized poly(4-hydroxystyrene)–b-poly(N-vinylamine) (PHS-b-PVAm) by Reversible Addition Fragmentation Chain-Transfer (RAFT) polymerization of 4-acetoxystyrene and N-vinylformamide with ‘Switchable’ RAFT agent to make a precursor polymer, poly(4-acetoxystyrene)-b-poly(N-vinylformamide) (PAcOS-b-PNVF), and by the subsequent hydrolysis. The reactivity of C-S double bond on the switchable RAFT agent gives a good control for the polymerization of both AcOS and NVF. Detailed synthesis and self-assembly behavior of PHS-b-PVAm diblock copolymer will be presented. |
