A general cocatalyst strategy for performance enhancement in nickel catalyzed ethylene(co)polymerization
文献摘要：
The tuning of olefin-polymerization catalyst properties through ligand modifications is efficient but re-quires complicated and costly syntheses.In this contribution,a simple Bu2Mg-based cocatalyst strategy is designed that can simultaneously enhance the catalytic properties(activity,thermal stability,polymer molecular weight,branching density,melting point,etc.)of various nickel catalysts(α-diimine nickel,pyridine imine nickel and iminopyridine-N-oxide nickel)in ethylene polymerization,and enable great product morphology control.For example,a simple α-diimine nickel catalyst can demonstrate polymer-ization activity of up to 1.29×107 g mol-1 h-1 and molecular weight of up to 1.90x106 g/mol in the pres-ence of Bu2Mg cocatalyst.The resulting polyethylenes exhibit excellent mechanical properties,with ten-sile stress of up to 47.4 MPa and strain of up to 1020％.This cocatalyst strategy is generally applicable to different nickel catalysts,and can lead to property enhancement in ethylene copolymerization with a series of polar comonomers such as methyl 10-undecylenate,10-undecylenic acid and 10-undecenol.
