Polyarylene oxide and method of producing the same

摘要

A method of producing a polyarylene oxide comprising a step of oxidative polymerization of a monomer represented by the general formula (1) in an organic solvent in the presence of a transition metal compound, wherein, Ar represents a benzene ring or a naphthalene ring, R¹ 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, R¹s may be the same or different, adjacent R¹s may mutually bond to form a ring; R² represents a single bond or an arylene group; R³ represents a hydrocarbon group optionally substituted or a trialkylsilyl group.
