While traditional polymerization of linear α-olefins (LAOs) typically provides amorphous, low Tg polymers, chain-straightening polymerization represents a route to semicrystalline materials. A series of α-diimine nickel catalysts were tested for the polymerization of various LAOs. Although known systems yielded amorphous or low-melting polymers, the sandwich α-diimines 3-6 yielded semicrystalline polyethylene comprised primarily of unbranched repeat units via a combination of uncommon regioselective 2,1-insertion and precision chain-walking events.
