We report the synthesis of a new class of strained macrocycle that performs well in ring-opening metathesis polymerization (ROMP). The polymerization displays chain growth characteristics with evidence of secondary metathesis in the form of chain transfer. The unique structure enables access to stilbene-based polymers that are traditionally prepared via uncontrolled polymerizations.

应变二苯乙烯基大环单体的开环易位聚合

我们报告了在开环复分解聚合（ROMP）中表现良好的一类新的应变大环的合成。聚合反应显示出链增长的特征，并以链转移的形式出现了二次复分解的迹象。独特的结构使人们能够获得传统上是通过不受控制的聚合反应制备的基于二苯乙烯的聚合物。
