Abstract:
The present invention relates to a method for manufacturing a polyarylene sulfide resin comprising: reacting a sulfoxide represented by the following formula (1) with a particular aromatic compound to obtain a poly(arylenesulfonium salt) having a particular constitutional unit; and dealkylating or dearylating the poly(arylenesulfonium salt) to obtain a polyarylene sulfide resin having a particular constitutional unit, wherein R1 represents an alkyl group having 1 to 10 carbon atoms, etc.; Ar1 and Ar2 each independently represent an arylene group optionally having a substituent; and Z represents a direct bond, etc.
