Abstract
Described are methods and compositions for inhibiting polymerization of a monomer (e.g., styrene) composition using a hydroxylated quinone antipolymerant. The hydroxylated quinone antipolymerant can be used with little or no nitroxyl group containing antipolymerant yet still provide excellent antipolymerant activity in a monomer-containing composition.
