Polymerization of 1,5-hexadiene with a bis(phenoxyimine) titanium catalyst system is reported. The microstructure of the polymer contains the expected methylene-1,3-cyclopentane units as well as the unexpected 3-vinyl tetramethylene units. A mechanism for formation of this polymer is proposed. This unusual reaction is also employed in the synthesis of vinyl-functional polypropylene copolymers and block copolymers with low polydispersity indices.
报道了用双（苯氧基亚胺）钛催化剂体系使1,5-己二烯聚合的情况。聚合物的微观结构包含预期的亚甲基-1,3-环戊烷单元以及意外的3-乙烯基四亚甲基单元。提出了该聚合物的形成机理。这种不寻常的反应还用于合成具有低多分散指数的乙烯基官能化聚丙烯共聚物和嵌段共聚物。
