Patent ID: 7291692

Claim:
A method of producing a polyarylene oxide comprising oxidative polymerization of a monomer shown by formula (1) in an organic solvent in the presence of a transition metal compound, wherein, Ar represents a benzene ring or a naphthalene ring, R 1 represents a hydrocarbon group optionally substituted, a hydrocarbonoxy group optionally substituted, or a halogen atom; a represents an integer of 0 to 5, and when a is 2 or more, R 1 s may be the same or different, and when two R 1 s bond to two adjacent carbon atoms on Ar, the R 1 s may mutually bond to form a ring; R 2 represents a single bond or an arylene group; R 3 represents a hydrocarbon group optionally substituted or a trialkylsilyl group.
