Supramolecular poly(vinyl acetate) PVAc 3-arms stars were successfully generated by Reversible Addition-Fragmentation chain Transfer (RAFT)-polymerized chains bearing hydrogenbonding heterocomplementary associating units. Chain Transfer Agents (CTA) bearing thymine- and diaminopyridine-based units were first synthesized and proved to mediate efficiently the polymerization of VAc. The binding ability of the chains in solution was then demonstrated by 1H NMR and GPC measurements, proving the formation of the supramolecular stars.
