Method of immediately terminating free-radical polymerisation processes

Method of immediately terminating free-radical polymerisation processes

立即终止自由基聚合反应的方法，该方法包括，向正进行着自由基聚合反应的体系中，添加一种含有吩噻嗪和至少50％(w/w)N-烷基吡咯烷酮的抑制剂溶液，其特征在于，所述抑制剂溶液还含有对甲氧基苯酚(MEHQ)。 Free radical polymerizations immediately terminated by a process comprising the addition of an inhibitor solution which contains phenothiazine and at least 50% (w/w) N-alkylpyrrolidone to a system...

Zusammenfassung:立即终止自由基聚合反应的方法，该方法包括，向正进行着自由基聚合反应的体系中，添加一种含有吩噻嗪和至少50％(w/w)N-烷基吡咯烷酮的抑制剂溶液，其特征在于，所述抑制剂溶液还含有对甲氧基苯酚(MEHQ)。 Free radical polymerizations immediately terminated by a process comprising the addition of an inhibitor solution which contains phenothiazine and at least 50% (w/w) N-alkylpyrrolidone to a system undergoing free radical polymerization, wherein the inhibitor solution also contains p-methoxyphenol (MEHQ).
