Abstract: The invention relates to a mixture of substances including one or more compounds with vinyl groups as component (A), and as component (B) - stabilizer containing one or more easily volatile nitroxyl compounds as component (b1), one or more not easily volatile nitroxyl compounds as component (b2), optionally one or more aromatic nitrocompounds as component (b3), optionally one or more iron compounds as component (b4). The invention also relates to stabilizers (B) containing the components (b1) & (b2), (b1), (b2) and (b3), (b1) (B2), (b4) and (b1),(b2), (b3) and (b4), and to a method for the inhibition of the premature polymerization of compounds containing vinyl groups during their refining or distillation by the addition of either stabilizer (B) or components from it as individual substances or at least as two groups of components. 10 claims
