摘要： This invention relates to a method for inhibiting polymerization of (meth)acrylic acid and its esters using a polymerization inhibitor which comprises at least one reduced halide-content azine dye-based compound. A process for producing reduced halide-content azine dye-based compounds using ion exchange resin technology is also provided.
摘要翻译： 本发明涉及一种用于抑制使用聚合抑制剂，含有至少一种降低卤化物含量吖嗪染料系化合物的（甲基）丙烯酸及其酯的聚合。 因此，提供一种用于生产使用离子交换树脂技术降低卤化物含量吖嗪染料系化合物的方法。
