| 20120203020 | MULTI-COMPONENT POLYMERIZATION INHIBITORS FOR ETHYLENICALLY UNSATURATED MONOMERS - The invention provides a composition and a method of using the composition for inhibiting the unwanted polymerization of ethylenically unsaturated monomers. The composition is prepared by reducing a nitroxide stable free radical to its corresponding hydroxylamine through reaction with a dialkyl/aryl hydroxylamine and subsequent addition of a polymerization prevention component selected from phenolic antioxidants, phenylenediamine and phenylenediamine derivatives, or phenothiazine and phenothiazine derivatives targeted towards ethylenically unsaturated monomers. The conversion of the nitroxide by the dialkyl/aryl hydroxylamine is to prevent it or the polymerization prevention component from being “spent” by reaction with each other, impurities or any other incompatible components. This allows previously incompatible combinations to now work effectively. In fact, the combination is more efficacious as the combination exerts a synergy due to the presence of various polymerization prevention reagents. The composition is a synergistic combination of various polymerization inhibition compounds for the inhibition of the unwanted polymerization of ethylenically unsaturated monomers. | 08-09-2012 |
