1. A method for manufacturing a polyarylene sulfide resin comprising:
reacting a sulfoxide represented by the following formula (1) with an aromatic compound represented by the following formula (2) to obtain a poly(arylenesulfonium salt) having a constitutional unit represented by the following formula (10); and dealkylating or dearylating the poly(arylenesulfonium salt) to obtain a polyarylene sulfide resin having a constitutional unit represented by the following formula (20): wherein in formula (1), (2), (10) or (20), R1 represents an alkyl group having 1 to 10 carbon atoms or an aryl group optionally having an alkyl group having 1 to 10 carbon atoms; R2a represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, —Ar4, —S—Ar4, —O—Ar4, —CO—Ar4, —SO2—Ar4 or —C(CF3)2—Ar4; R2b represents a direct bond, —Ar6—, —S—Ar6—, —O—Ar6—, —CO—Ar6—, —SO2—Ar6— or —C(CF3)2—Ar6—; Ar1, Ar2, Ar3b and Ar6 each independently represent an arylene group optionally having a substituent; Ar3a and Ar4 each independently represent an aryl group optionally having a substituent; Z represents a direct bond, —S—, —O—, —CO—, —SO2— or —C(CF3)2—; and X− represents an anion. |
