摘      要：In this work,a series of molybdovanadophosphoric heteropoly acid quaternary ammonium salts H_（3＋x）PMo_（12 -x）V_xO40-T were synthesized and employed as a reaction inhibitor in the selfpolymerization of methyl methacrylate（MMA）.The polymerization inhibition effect of H_（3＋x）PMoPMo_（12 -x）V_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＋x）PMoPMo_（12 -x）V_xO40-T）,and the polymerization inhibition was also affected by the number of vanadium atoms in the H_（3＋x）PMo_（12 -x）V_xO40-T .Furthermore,cyclic voltammograms（CV）was used to probe the mechanism of the inhibition reaction with H3＋*** result of CV indicates that the inhibition reaction is an oxidation–reduction reaction.H_（3＋x）PMo_（12 -x）V_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＋x）PMo_（12 -x）V_xO40-T.
