FIELD: chemistry.
SUBSTANCE: present invention relates to a composition of an amine-based additive for controlling and inhibiting polymerisation of vinyl aromatic monomers, including styrene containing (a) one or more of nitroxide (i.e. nitroxy) compounds and (b) one or more of aromatic nitro compounds; characterised by that said composition additionally contains one or more of (c) amines, characterised by that said amine contains hydroxyl alkyl tertiary amines, including tris(2-hydroxypropyl) amine (TIPA); Ν,Ν,Ν',Ν'-tetrakis(2-hydroxypropyl) ethylene-diamine (Quadrol); N,N,N',N'-tetrakis(2-hydroxyethyl) ethylene-diamine (THEED) or their mixture. Present invention also relates to a method of monitoring and inhibiting polymerisation of vinyl aromatic monomers, including styrene, by adding proposed composition, as well as methods of producing and using proposed composition for controlling and inhibiting said polymerisation.
EFFECT: control and inhibition of polymerisation of vinyl aromatic monomers.
