Embodiment Construction

[0024] In order to overcome the above-mentioned problems of the prior art and achieve the above-mentioned object of the present invention, the inventors have found that when one or more tertiary amines are added to a compound containing one or more aromatic compounds and one or more nitroxide When used in the composition of aromatic compounds and nitroxide compounds, the polymerization control and inhibition efficiency of compositions comprising aromatic compounds and nitroxides is not only substantially improved, but surprisingly and unexpectedly, by including one or more tertiary amines Substantially reduced and minimal amounts of aromatic compounds and nitroxides in compositions with one or more aromatic compounds and one or more nitroxides, including aromatic vinyl of styrene Polymerization of the monomers is also controlled and inhibited to acceptable levels, making the present compositions both economical and environmentally friendly.
