  Disclosed herein is a method for inhibiting and retarding the premature polymerization and the polymer growth of ethylenically unsaturated monomers comprising adding to said monomers an effective amount of at least one inhibitor that is a sulfonated nitrophenol of the formula: (I) wherein: R1, R2, and R3 are independently selected from the group consisting of hydrogen, alkyl, NO2, and S03H, provided that at least one of R,, R2, and R3 is NO2 and at least one of R1, R2, and R3 is SO3H. In a preferred embodiment, at least one additional inhibitor selected from the group consisting of nitroxyl compounds, nitrosoanilines, nitrophenols, amines, and mixtures thereof is also added.

  本文揭示了一种抑制和延缓乙烯基不饱和单体的聚合物的过早聚合和聚合物生长的方法，包括向所述单体中添加至少一种抑制剂，其为公式（I）的磺化硝基苯酚的有效量：其中：R1、R2和R3是独立选择自氢、烷基、NO2和S03H的群组，前提是R1、R2和R3中至少有一个是NO2，且R1、R2和R3中至少有一个是SO3H。在优选实施例中，还添加了至少一种来自亚硝基化合物、亚硝基苯胺、硝基苯酚、胺和它们的混合物的附加抑制剂。
