Abstract:
A mixture comprising(A) at least one vinyl-containing compound, (B) a stabilizer comprising (b1) a nitroxyl compound of a secondary amine having no hydrogen atoms on the &agr; carbon atoms, whose vapor pressure at the boiling point of the lowest-boiling vinyl-containing compound from (A) is from 0.01 to 50% of the vapor pressure of the lowest-boiling vinyl-containing compound (A), or a mixture of nitoxyl compounds of secondary amines having no hydrogen atoms on the &agr; carbon atoms, in which the vapor pressure of the highest-boiling nitroxyl compound at the boiling point of the lowest-boiling vinyl-containing compound from (A) is from 0.01 to 50% of the vapor pressure of the lowest-boiling vinyl-containing compound from (A), (b2) a nitroxyl compound of a secondary amine having no hydrogen atoms on the &agr; carbon atoms, whose vapor pressure at the boiling point of the highest-boiling vinyl-containing compound from (A) is less than 0.01% of the vapor pressure of the highest-boiling vinyl-containing compound from (A), or a mixture of nitroxyl compounds of secondary amines having no hydrogen atoms on the &agr; carbon atoms, in which the vapor pressure of the lowest-boiling nitroxyl compound at the boiling point of the highest-boiling vinyl-containing compound from (A) is less than 0.01% of the vapor pressure of the highest-boiling vinyl-containing compound from (A), wherein (b1) and (b2) the vapor pressure of the nitroxyl compound and the vapor pressure of a vinyl-containing compound at the boiling point of the vinyl containing compound is taken as the reference, and optionally (b3) at least one aromatic nitro compounds and/or (b4) at least one iron compounds.
