COMPOSITION THAT PREVENTS PREMATURE POLYMERIZATION OF VINYL AROMATIC COMPOUNDS, AND METHOD OF PREVENTION OF POLYMERIZATION OF VINYL AROMATIC COMPOUNDS Russian patent published in 1998 - IPC

Abstract RU 2116285 C1

FIELD: chemistry of polymers. SUBSTANCE: present invention describes inhibition of polymerization of vinyl aromatic compound such as styrene while it is distilled or purified in the presence of at least one stable nitroxyl compound together with one aromatic nitro compound. The present invention makes it possible to increase distillation temperature of vinyl aromatic compounds to form minium polymers. EFFECT: improved properties of the composition.
