A method for inhibiting the premature polymerization of styrenic monomers is disclosed wherein the method comprises adding to said monomers a combination of: (A) at least one inhibitor that is a sulfonic acid compound in a concentration sufficient to initiate cationic polymerization of said styrenic monomers at any point of the manufacturing or purification process and cause a resulting temperature increase; and (B) at least one amine in a concentration sufficient to reduce said cationic polymerization and said temperature increase; whereby an uncontrolled exothermic reaction between said sulfonic acid compound and said styrenic monomers will be prevented.
本发明公开了一种抑制苯乙烯单体过早聚合的方法,其中该方法包括向所述单体中加入以下物质的组合:(A) 至少一种磺酸化合物抑制剂,其浓度足以在制造或提纯过程的任何阶段引发所述苯乙烯单体的阳离子聚合,并导致温度升高;以及 (B) 至少一种胺,其浓度足以减少所述阳离子聚合和所述温度升高;从而防止所述磺酸化合物和所述苯乙烯单体之间发生不受控制的放热反应。
