Inhibiting polymerization of vinyl aromatic monomers |
| 摘要 |
When a nitroxyl compound is heated in an oxygen-free atmosphere with a vinyl aromatic monomer at 50-140 DEG C. for up to 60 days, it forms an activated inhibitor mixture which is superior to the nitroxyl compound itself in preventing the premature polymerization of a vinyl aromatic monomer during its processing and purification.
