Abstract
Disclosed are compositions and methods for inhibiting polymerization of ethylenically unsaturated monomers. The compositions comprise a methoxyphenol compound selected from the group consisting eugenol and 2-tert-butyl-4-hydroxyanisole and a phenylenediamine compound. The methods comprise adding from about 1 to about 10,000 parts per million to the ethylenically unsaturated monomer during processing.
