Synthesis and Self-Assemble Behavior of Block Copolymerization of Vinyl Acetate and N-Vinylacetamide

Article Preview

Abstract:

Polymerizations of VAc was carried out using AIBN as the initiator and DIP as the MADIX agent precursor. Then, block copolymer PVAc-b-PNVA had been synthesized by RAFT radical polymerization in the presence of PVAc-DIP as macro CTA. The length of blocks could be tuned by changing the molar ratio of NVA and VAc. Block copolymer PVAc-b-PNVA self-assembled into micelles in solution, and underwent microphase separation in bulk state.
