Polymerization inhibition of vinyl aromatic monomer |
| abstract |
(57) Abstract: Provided are a composition and a method for preventing premature polymerization of an easily polymerizable vinyl aromatic monomer. A stable hindered nitroxyl compound is provided. 1 to 50% by weight and a vinyl aromatic compound 99.9 to 5 0% by weight of the mixture in an oxygen-free atmosphere at 50-14% Activated nitroxyl, a product produced by heating at 0 ° C. for 0.5 hours to 60 days, which can provide enhanced inhibition of premature polymerization of vinyl aromatic monomers. Vinyl aromatic monomer mixture. A method for inhibiting early polymerization of a vinyl compound, comprising mixing an effective inhibitory effective amount of the activated mixture with a vinyl aromatic compound. Use of the above activated mixture to prevent premature polymerization of the vinyl aromatic compound during distillation and purification. |
