Composition for inhibiting monomer polymerization comprising a nitroxide inhibitor, a quinone methide retarder, and an amine stabilizer

摘要

A composition and method for inhibiting polymerization of a monomer (eg, styrene) composition using an N-O polymerization inhibitor, a quinone methide polymerization retarder, and an amine stabilizer having a primary and/or secondary amine group are described. In the mixture, the amine stabilizer can prevent the antagonistic effect and provide greater antipolymerization activity. In turn, the mixture suppresses device contamination and improves the purity of the monomer stream.
