研究了在125℃布拉特自由基存在下，苯乙烯(自引发和偶氮二异丁腈引发)的可控聚合。当使用自由基引发剂时，没有诱导期。根据紫外光谱和MALDI质谱学研究，确定布拉特自由基在聚合的初始阶段被完全消耗，插入到几乎所有的大分子中。所制备的聚苯乙烯具有在后聚合中重新初始化和合成嵌段共聚物的能力。
Controlled polymerization of styrene (both self-initiated and initiated with azobisisobutyronitrile) in the presence of Blatter’s radical at 125 °C was studied. When using the radical initiator, there is no induction period. On the basis of UV spectroscopy and MALDI massspectrometry studies, it was established that the Blatter radical is completely consumed at the initial stage of the polymerization, inserting into almost all macromolecules. The prepared polystyrene exhibits the ability to reinitialization in post-polymerization and the synthesis of block copolymers.
