  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.

  本发明描述了抑制单体（如苯乙烯）聚合的组合物和方法，组合物包括甲脒醌聚合延缓剂和含氧胺化合物（叔胺或羟胺）。在混合物中，含氧胺化合物可提高甲脒醌类聚合延缓剂的功效，并提供更强的抗聚合活性。反过来，混合物还能减少或防止装置堵塞，提高单体流的纯度。

  Described are compositions and methods for inhibiting polymerization of a monomer (e.g., styrene) composition, which use an N—O polymerization inhibitor, a quinone methide polymerization retarder, and an amine stabilizer having a primary and/or secondary amine group. In a mixture, the amine-based stabilizer can prevent antagonistic effects and can provide greater antipolymerant activity. In turn, the mixture inhibits apparatus fouling and improves the purity of monomer streams.

  描述了抑制单体（如苯乙烯）组合物聚合的组合物和方法，其中使用了一种 N-O 聚合抑制剂、一种醌甲醚聚合延缓剂和一种具有伯胺和/或仲胺基团的胺稳定剂。在混合物中，胺基稳定剂可以防止拮抗作用，并提供更强的抗聚合活性。反过来，混合物可抑制装置堵塞，提高单体流的纯度。

  Described are methods and composition for inhibiting polymerization of a monomer (e.g., styrene) composition using an aminated quinone antipolymerant, such as an aminated benzoquinone or aminated naphthoquinone antipolymerant having one or more secondary or tertiary amine group(s). The aminated quinone antipolymerant can be used with little or no nitroxyl group containing antipolymerant yet still provide excellent antipolymerant activity in a monomer-containing composition.

  描述了使用胺化醌类抗聚合剂（如具有一个或多个仲胺或叔胺基团的胺化苯醌或胺化萘醌类抗聚合剂）抑制单体（如苯乙烯）组合物聚合的方法和组合物。胺化醌类抗聚合剂可与含少量或不含硝基的抗聚合剂一起使用，但仍能在含单体的组合物中提供优异的抗聚合活性。

  Disclosed herein are systems and methods for monitoring and controlling a nitroxide-based polymerization inhibitor in vinyl-based monomers. A dosage of the nitroxide-based polymerization inhibitor is provided in the vinyl-based monomers. A residual concentration of the nitroxide-based polymerization inhibitor is measured substantially in real time, and an optimized dosage of the nitroxide-based polymerization inhibitor is provided in response to the measured residual concentration.
