Abstract
Described are compounds, compositions, and methods that include a nitrogen- and oxygen-containing aromatic compound, such as an aminophenol-based compound, which can be used for inhibiting polymerization of a monomer (e.g., styrene) composition. The compound includes a tertiary amine group wherein the nitrogen is attached to carbon-containing groups, and at least one of oxygen atom separated from the nitrogen by one or more carbon atoms. The antipolymerant can provide excellent antipolymerant activity in a monomer-containing composition.
