Compositions, comprised of a dinitrophenol in an aromatic hydrocarbon solvent, which compositions further comprise a sufficient amount of a phenylenediamine such that a greater amount of dinitrophenol is in solution than would be present in solution if such phenylenediamine were not present, exhibit unexpectedly desirable low temperature stability, and may be diluted with additional solvent to be employed as polymerization inhibitors for vinyl aromatic compounds. |
