摘要: A C2-symmetric Ni(II) catalyst was found to polymerize α-olefins with high levels of ω,2-regiochemistry. The resulting products are ethylene−propylene-type copolymers methylene sequences precise length between methyl branches. Modification reaction conditions can introduce ω,1-enchainments into the polymers which increases average
