The invention relates to composition comprising: at least one free radical polymerizable vinyl compound; and an active amount of inhibition composition comprising metal ions, halogen ions and a ligand having a donor atom selected from oxygen, nitrogen, sulfur, phosphorus and a combination thereof, the metal ions being selected from ions of Ti, Mo, Re, Ru, Fe, Rh, Ni, Pd, Co, Os, Cu and any combination thereof; wherein the composition is free of a nitroxyl compound of a secondary amine having no hydrogen atom on α-C atom. A method for inhibiting the premature polymerization of at least one free radical polymerizable vinyl compound, comprising: adding an active amount of the inhibition composition to the at least one free radical polymerizable vinyl compound. |
