    <description descriptionType="Abstract">Photoinitiated cationic polymerization of vinyl ethers in aqueous medium by using diphenyliodonium iodide (DPII) in the presence of a water-tolerant Lewis acid, ytterbium triflate (Yb(OTf)(3)), was reported. The polymerizations were performed in heterogeneous systems consisting of an aqueous phase containing Yb(OTf)(3) and photoinitiator and an organic phase of acetonitrile containing monomer. The polymerization consists of two-steps; (i) photoinduced adduct formation and hi) subsequent propagation with the aid of Yb(OTf)(3). The fast polymerization exhibited an explosive character so that the monomer conversion and molecular weights of the resulting polymers are very dependent on the experimental conditions, such as temperature, stirring manner and rate.</description>
