Summary Two unsaturated ester-containing vinyl ethers, 2-vinyloxyethyl acrylate $$(\mathop 1\limits_ )$$ and sorbate $$(\mathop 2\limits_ )$$ , were polymerized by the hydrogen iodide/iodine (HI/I2) initiating system in toluene at −15 or −40°C, to give “living” polymers, having a very narrow molecular weight distribution (Mw/¯Mn=1.10–1.15) and crosslinkable via their pendant C=C double bonds. The number-average molecular weight of the polymers increased in direct proportion to conversion, and further increased on addition of a new monomer feed to a polymerized reaction mixture. According to 1H and 13C NMR structural analysis, the polymerization proceeds exclusively via the vinyloxyl group of the potentially bifunctional monomers without undesirable side reactions of the unsaturated ester pendants.
