A highly active Ni(II)-triadamantylphosphine catalyst for ultrahigh-molecular-weight polyethylene synthesis

Here we report that the tri-1-adamantylphosphine-nickel complex [Ad(3)PNiBr(3)](-)[Ad(3)PH](+) upon activation with an alkylaluminoxane catalyzes the polymerization of ethylene to ultrahigh-molecular-weight, nearly linear polyethylene (M(n) up to 1.68 × 10(6) g mol(−1)) with initial activities reach...

description Here we report that the tri-1-adamantylphosphine-nickel complex [Ad(3)PNiBr(3)](-)[Ad(3)PH](+) upon activation with an alkylaluminoxane catalyzes the polymerization of ethylene to ultrahigh-molecular-weight, nearly linear polyethylene (M(n) up to 1.68 × 10(6) g mol(−1)) with initial activities reaching 3.7 million turnovers per h(−1) at 10 °C. Copolymerizations of ethylene with α-olefins such as 1-hexene and 1-octadecene, as well as tert-butyldimethyl(dec-9-en-1-yloxy)silane give the corresponding copolymers with no decrease in activity.
