US 10,982,049 B2 · Polyarylene sulfide resin and manufacturing method therefor, poly(arylene sulfonium salt) and manufacturing method therefor, and sulfoxide

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.

Claims4

Dependent claims

A polyarylene sulfide resin having a constitutional unit represented by the following formula (20):

wherein
R2b represents —Ar6— or —C(CF3)2—Ar6—;
Ar1, Ar2, and Ar3b each independently represent a phenylene group or a naphthylene group;
Ar6 represents an arylene group optionally having a substituent;
and
Z represents a direct bond, —S—, —O—, or —C(CF3)2—;
wherein
Z is —O—, or —C(CF3)2— when Ar1, Ar2 and Ar3b are each a 1,4-phenylene group, R2b is —Ar6— and Ar6 is a 1,4-phenylene group.
