  COMPOSITIONS OF OXYGENATED AMINES AND QUINONE METHIDES AS ANTIFOULANTS FOR VINYLIC MONOMERS

  摘要：

  Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition a quinone methide polymerization retarder and an oxygen-containing amine compound that is a tertiary amine or hydroxylamine. In a mixture, the oxygen-containing amine compound improves the efficacy of the quinone methide polymerization retarder and provides greater antipolymerant activity. In turn, the mixture reduces or prevents apparatus fouling and improves the purity of monomer streams.

  Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition a quinone methide polymerization retarder and an ammonium salt. In a mixture, the ammonium salt improves the efficacy of the quinone methide polymerization retarder and provides greater antipolymerant activity. In turn, the mixture reduces or prevents apparatus fouling and improves the purity of monomer streams.
