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 R 1 represents an alkyl group having 1 to 10 carbon atoms, etc.; Ar 1 and Ar 2 each independently represent an arylene group optionally having a substituent; and Z represents a direct bond, etc.

First claim

The invention claimed is:

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

wherein
R 2b represents —Ar 6 — or —C(CF 3 ) 2 —Ar 6 —;
Ar 1 , Ar 2 , and Ar 3b each independently represent a phenylene group or a naphthylene group;
Ar 6 represents an arylene group optionally having a substituent; and
Z represents a direct bond, —S—, —O—, or —C(CF 3 ) 2 —;
wherein
Z is —O—, or —C(CF 3 ) 2 — when Ar 1 , Ar 2 and Ar 3b are each a 1,4-phenylene group, R 2b is —Ar 6 — and Ar 6 is a 1,4-phenylene group.

2. The polyarylene sulfide resin of claim 1 , wherein the melting point of the polyarylene sulfide resin is in a range of 100 to 400° C.

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

wherein
R 2b represents a direct bond, —Ar—, or —C(CF 3 ) 2 —Ar 6 —;
Ar 1 , Ar 2 , and Ar 3b each independently represent a phenylene group or a naphthylene group;
Ar 6 represents an arylene group optionally having a substituent;
Z represents —S—, —O—, or —C(CF 3 ) 2 —;
wherein
Z is —C(CF 3 ) 2 — when Ar 1 , Ar 2 and Ar 3b are each a 1,4-phenylene group and R 2b is a direct bond; and
Z is —O—, or —C(CF 3 ) 2 — when Ar 1 , Ar 2 and Ar 3b are each a 1,4-phenylene group, R 2b is —Ar 6 — and Ar 6 is a 1,4-phenylene group.

4. The polyarylene sulfide resin of claim 3 , wherein the melting point of the polyarylene sulfide resin is in a range of 100 to 400° C.
