Abstract
The reactivity of 5-hexenyl-9-BBN in Ziegler-Natta copolymerization with α-olefins, e.g., propylene, 1-butene, and 1-octene is investigated. The monomer reactivities were studied by reactivity ratio, copolymer compositions during the reaction and copolymer microstructure. In general, the borane monomer can be effectively incorporated into polyolefins with controllable concentrations and locations. Due to the excellent stability of boranes to the catalyst and solubility of boranes in hydrocarbon solution, the borane monomer behaves as a high α-olefin monomer in Ziegler-Natta polymerization. In turn, the trialkylboranes in copolymers are easily converted to various functional groups under homogeneous or heterogeneous reaction conditions
