A METHOD FOR INHIBITING PREMATURE POLYMERIZATION OF VINYL AROMATIC MONOMERS |
| 摘要 |
Nitroxyl inhibitors in combination with some oxygen reduce the premature polymerization of vinyl aromatic monomers during the manufacturing processes for such monomers. Even small quantities of air used in combination with the nitroxyl inhibitors result in vastly prolonged inhibition times for said monomers.
