研究了[（π-烯丙基）NiOCOCF_3]_2与环状联烯的配位聚合，以高产率制备窄分子量分布的聚合物。聚合反应以活性机理进行，所得聚合物的分子量与单体投料比呈线性关系。特别地，1，2-环壬二烯（即，具有显著环应变的单体）与无环单体相比进行得非常快。
The coordination polymerization of cyclic allenes by [(π-allyl)NiOCOCF3]2 was investigated to produce polymers with narrow molecular weight distributions in high yields. The polymerization proceeded in a living mechanism, and the molecular weight of the resulting polymer had a linear relationship with the monomer feed ratio. Especially, the polymerization of 1,2-cyclononadiene (i.e., a monomer with substantial ring strain) proceeded dramatically fast compared with acyclic monomers.
