摘要: 본발명은에틸렌계불포화단량체의원치않는중합을억제하기위한조성물및 이조성물을사용하는방법을제공한다. 이러한조성물은니트록시드안정유리라디칼을디알킬/아릴하이드록실아민과의반응을통해상응하는하이드록실아민으로환원한후, 에틸렌계불포화단량체를표적으로하는페놀계항산화제, 페닐렌디아민및 페닐렌디아민유도체, 또는페노티아진및 페노티아진유도체로부터선택되는중합방지성분을첨가함으로써제조된다. 디알킬/아릴하이드록실아민에의한니트록시드의전환은, 이니트록시드또는중합방지성분이, 이들성분상호간, 불순물또는임의의기타다른병용할수 없는성분들과의반응에의해 "소모"되지않도록하기위한것이다. 이에따라이전에는병용할수 없던조합물이이제효과적으로작용할수 있게된다. 실제로, 이러한조합물은다양한중합방지시약들의존재로인하여상승효과를나타내므로, 이러한조합물은더 효과적이다. 이러한조성물은에틸렌계불포화단량체의원치않는중합을억제하기위한, 다양한중합억제화합물의상승조합물이다.

摘要: 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.
