Polymerization of methyl methacrylate in the presence of 2,5-di-tert-butyl-p-benzoquinone is a combination of two processes: inhibited and controlled radical polymerization. The adduct of chain propagation radicals and p-quinone formed due to the inhibited polymerization is a macroinitiator of controlled radical polymerization. The fraction of the pseudo-living process is determined by the concentration of p-quinone in the starting polymerized composition. Post-polymerization proceeds via the reversible inhibition mechanism.

2,5-二叔丁基对苯醌存在下甲基丙烯酸甲酯的聚合

在 2,5-二叔丁基对苯醌存在下甲基丙烯酸甲酯的聚合是两个过程的组合：抑制和受控自由基聚合。由于聚合受到抑制而形成的链增长自由基和对醌的加合物是受控自由基聚合的大分子引发剂。假活过程的分数由起始聚合组合物中对醌的浓度决定。后聚合通过可逆抑制机制进行。
