Abstract
The present invention relates to an improved amine based additive composition for control and inhibition of polymerization of aromatic vinyl monomers, particularly of styrene comprising one or more quinone methide compounds, one or more phenolic compounds and further comprising at least one aliphatic tertiary amine containing —OH group in the alkyl chain. In one embodiment, the present invention also relates to method of use of presently provided composition. In another embodiment, the present invention also relates to method of controlling and inhibiting polymerization of aromatic vinyl monomers, particularly of styrene by employing presently provided composition. In still another embodiment, the present invention also relates to method of preparation of presently provided composition.
