摘要: Precise control over macromolecular structures is a central goal and remains great challenge in synthetic polymer chemistry. We report herein the living isomerization polymerization of allycyclohexane (ACH) using α-diimine nickel catalysts with high regioselectivity. The influences catalyst structure, cocatalyst, temperature on ACH were studied detail. structure polyallycyclohexanes (PACHs) was precisely controlled by combination regioselectivity under optimized conditions. A mechanistic model involving 2,1-insertion selectivity chain walking proposed. Well-defined polyallycyclohexane-b-poly(1-hexene) copolymers (PACH-b-PH) cyclic units synthesized sequential monomer addition.
