导论.固相聚合是控制聚合物结构的有效方法。几种二炔和二烯单体经历固态聚合，导致具有受控化学和立体结构的聚合物。然而，除了使用固体基质的反应（包合聚合）之外，还没有乙烯基单体的固态聚合的明确实例。3在本研究中，我们发现乙烯基单体二苯并富烯（DBF）与氧在固态下共聚得到结构为1的聚合物。我们最近证实4，DBF是一种高反应性的单体在乙烯基均聚在溶液中，尽管其庞大的结构类似1，1-二苯基乙烯，5不均聚。DBF在固态聚合中也是反应性的。
Introduction. Solid-state polymerization is an efficient method in controlling polymer structure. Several diyne and diene monomers undergo solid-state polymerization, leading to polymers with controlled chemical and stereostructures. 1, 2 However, there has been no clear examples of solid-state polymerization of vinyl monomers except for the reactions using solid matrices (inclusion polymerization). 3 In this study, we found that dibenzofulvene (DBF), a vinyl monomer, copolymerizes with oxygen in the solid state to give a polymer with structure 1. We recently reported4 that DBF is a highly reactive monomer in vinyl homopolymerization in solution despite its bulky structure resembling 1, 1-diphenylethylene, 5 which does not homopolymerize. DBF is also reactive in the solid-state polymerization.
