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.

AbstractTetrahydrofuran-soluble block copolymer of 2,2-dimethyltrimethylene carbonate with adipic anhydride [poly(DTC-b-AA)] containing 64.7/35.3 DTC/AA in molar ratio with Mn of 12.3 104 and Mw/Mn of 1.64 was synthesized by lanthanum tris(2,6-di-tert-butyl-4- methylphenolate) catalyst at 25 C in 32 min. The copolymer was characterized by SEC, 1H NMR and DSC. Copolymers with AA block from 8.5 % to 50.8 % were prepared by changing the solvent and feeding ratio of DTC/AA.
