    • PROBLEM TO BE SOLVED: To provide a polymerization inhibitor exhibiting effects on an aromatic vinyl compound in an amount smaller than that of a conventionally used polymerization inhibitor; and to provide a method for inhibiting the polymerization of the aromatic vinyl compound by using the inhibitor.
      SOLUTION: The polymerization inhibitor of the aromatic vinyl compound contains an N-nitroso compound having sterically hindering tertiary hydrocarbon group or alicyclic hydrocarbon group such as N-nitroso-N-cyclohexylaniline and N-nitroso-N-(tert-butyl)aniline as an active ingredient. Preferably, an N-oxyl compound such as 1-oxyl-2,2,6,6-tetramethylpiperidin-4-ol and 1-oxyl-2,2,6,6-tetramethylpiperidin-4-one is used in combination with the N-nitroso compound.
