1, 2 -bis -adducts of stable nitroxides with substituted ethylenes and stabilized compositions

制备了稳定的受阻胺硝基氧化合物与取代的乙烯的1，2-双加合物，通过将等当量的硝酰基化合物与例如为苯乙烯或丙烯酸酯的烯不饱和化合物反应。这些加合物为十分有效的抑制剂以防止烯不饱和单体在蒸馏、加工或贮存时的早期聚合。 1,2-Bis-adducts of stable hindered nitroxide compounds with substituted ethylenes of formulas (I) & (II) are prepared by reacting two equivalents of nitroxyl compound with an ethylenically...

Zusammenfassung:	制备了稳定的受阻胺硝基氧化合物与取代的乙烯的1，2-双加合物，通过将等当量的硝酰基化合物与例如为苯乙烯或丙烯酸酯的烯不饱和化合物反应。这些加合物为十分有效的抑制剂以防止烯不饱和单体在蒸馏、加工或贮存时的早期聚合。 1,2-Bis-adducts of stable hindered nitroxide compounds with substituted ethylenes of formulas (I) & (II) are prepared by reacting two equivalents of nitroxyl compound with an ethylenically unsaturated compound such as styrene or an acrylate ester. These adducts are very effective inhibitors to prevent the premature polymerization of ethylenically unsaturated monomers when such monomers are distilled, processed or stored.
