<p>Use of a polymerization inhibitor for stabilization of olefinically unsaturated monomer(s) (I) comprises mixing a polymerization inhibitor (mixture) of 0-100 wt.% aliphatic or cyclic oxoammonium salt (IIA) and 100-0 wt.% aliphatic or cyclic hydroxylammonium salt (IIB), having (in)organic anions, with (I) or a monomer mixture containing (I). Use of a polymerization inhibitor for stabilization of olefinically unsaturated monomer(s) (I) comprises mixing a polymerization inhibitor (mixture) of 0-100 wt.% aliphatic or cyclic oxoammonium salt (IIA) and 100-0 wt.% aliphatic or cyclic hydroxylammonium salt (IIB) of the following formulae with (I) or a monomer mixture containing (I): Y 1-C(R 1)(R 2)- +>N(=O)-(R 3)(R )4)-Y 2 (IIA); Y 1-C(R 1)(R 2)- +>NH(OH)-(R 3)(R )4)-Y 2 (IIB); R 1, R 2, R 3, R 41-4 C alkyl and may be the same or different; Y 1, Y 21-4 C alkyl and may be the same or different or together form an optionally substituted ring system; X ->an (in)organic anion . An independent claim is included for a monomer composition containing 0-100 wt.% (IIA) and 100-0 wt.% (IIB) and (I).</p> |
