Nickel dioctanoate → HCID 22229092, compound

A hexane solution of nickel octanoate was reacted with hexafluoroantimonic acid at −10° C. at a molar ratio of 1:1, and a precipitate of nickel bis(hexafluoroantimonate) [Ni(SbF6)2] formed as a by-product was removed by filtration. The resulting product was diluted with toluene. A reaction vessel was charged with 0.40 mmol (as a nickel atom) of the resulting hexafluoroantimonic acid-modified product of nickel octanoate, 1.2 mmol of boron trifluoride ethyl etherate, 8.0 mmol of methylalumoxane, 0.4 mmol of 1,5-cyclooctadiene and 8.0 mmol of methyltriethoxysilane in the order of methyltriethoxysilane, 1,5-cyclooctadiene, methylalumoxane, boron trifluoride ethyl etherate and the hexafluoroantimonic acid-modified product of nickel octanoate, and polymerization was initiated. The polymerization was conducted at 30° C. for 3 hours, and methanol was added to terminate the polymerization. The conversion rate of the monomers to the copolymer was 73%.
