A method for producing a polyarylene comprising polymerizing only a dihalobiphenyl compound represented by the formula (1):
wherein A represents a C1-C20 alkoxy group etc., R 1 represents a fluorine atom etc., X 1 represents a chlorine atom etc., and k represents an integer of 0 to 3, or a dihalobiphenyl compound represented by the formula (1) with an aromatic compound represented by the formula (2):
or an aromatic compound represented by the formula (3):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒX 3 -Ar 5 -X 3 €ƒ€ƒ€ƒ€ƒ€ƒ(3)
wherein a, b and c represents 0 or 1, n represents an integer of 5 or more, Ar 1 , Ar 2 , Ar 3 and Ar 4 represents a divalent aromatic group etc., Y 1 and Y 2 represents a single bond etc., Z 1 and Z 2 represents -O- or -S-, and X 2 and X 3 represent a chlorine atom etc.,
in the presence of catalytic amounts of a divalent nickel compound, a trivalent phosphorus ligand and zinc. |
