摘要: In this work, a series of molybdovanadophosphoric heteropoly acid quaternary ammonium salts (H_3+xPMo_12-xV_xO₄₀-T) were synthesized and employed as a reaction inhibitor in the selfpolymerization of methyl methacrylate (MMA). The polymerization inhibition effect of H_3+xP-Mo_12-xV_xO₄₀-T with different number of vanadium atoms and reaction dosages was investigated using differential scanning calorimetry (DSC). It shows that the inhibitory effect was improved with the increasing dosages of H_3+xPMo_12-xV_xO₄₀-T, and the polymerization inhibition was also affected by the number of vanadium atoms in the H_3+xPMo_12-xV_xO₄₀-T. Furthermore, cyclic voltammograms (CV) was used to probe the mechanism of the inhibition reaction with H_3+xPMo_12xV_xO₄₀-T. The result of CV indicates that the inhibition reaction is an oxidation-reduction reaction. H_3+xPMo_12-xV_xO₄₀-T can react directly with the MMA monomer radicals, which eliminated the MMA monomers, and therefore the self-polymerization of the MMA can be effectively inhibited by H_3+xPMo_12-xV_xO₄₀-T.

Abstract: In this work, a series of molybdovanadophosphoric heteropoly acid quaternary ammonium salts (H_3+xPMo_12-xV_xO₄₀-T) were synthesized and employed as a reaction inhibitor in the selfpolymerization of methyl methacrylate (MMA). The polymerization inhibition effect of H_3+xP-Mo_12-xV_xO₄₀-T with different number of vanadium atoms and reaction dosages was investigated using differential scanning calorimetry (DSC). It shows that the inhibitory effect was improved with the increasing dosages of H_3+xPMo_12-xV_xO₄₀-T, and the polymerization inhibition was also affected by the number of vanadium atoms in the H_3+xPMo_12-xV_xO₄₀-T. Furthermore, cyclic voltammograms (CV) was used to probe the mechanism of the inhibition reaction with H_3+xPMo_12xV_xO₄₀-T. The result of CV indicates that the inhibition reaction is an oxidation-reduction reaction. H_3+xPMo_12-xV_xO₄₀-T can react directly with the MMA monomer radicals, which eliminated the MMA monomers, and therefore the self-polymerization of the MMA can be effectively inhibited by H_3+xPMo_12-xV_xO₄₀-T.
