Polyarylene sulfide resin and manufacturing method therefor, poly(arylenesulfonium 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 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.

The invention claimed is: 
     
       1. A poly(arylenesulfonium salt) having a constitutional unit represented by the following formula (10): 
       
         
           
           
               
               
           
         
         wherein 
         R 1  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; 
         R 2b  represents a direct bond, —Ar 6 —, —S—Ar 6 —, —O—Ar 6 —, —CO—Ar 6 —, —SO 2 —Ar 6 — or —C(CF 3 ) 2 —Ar 6 —; 
         Ar 1 , Ar 2 , Ar 3b  and Ar 6  each independently represent an arylene group optionally having a substituent; 
         Z represents a direct bond, —S—, —O—, —CO—, —SO 2 — or —C(CF 3 ) 2 —; and 
         X −  represents an anion, wherein 
         Z is a direct bond, —CO—, —SO 2 — or —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 —S—, —O—, —CO—, —SO 2 — 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. A sulfoxide represented by the following formula (5): 
       
         
           
           
               
               
           
         
         wherein 
         R 1  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; 
         Ar 1  and Ar 2  each independently represent an arylene group optionally having a substituent, wherein the substituent is chosen from the group consisting of an alkyl group having 1 to 10 carbon atoms, a hydroxy group, a mercapto group, a carboxyl group, and a sulfo group; and 
         Z represents a direct bond, —S—, —O—, —CO—, —SO 2 — or —C(CF 3 ) 2 —, wherein 
         R 1  is an alkyl group having 2 to 10 carbon atoms or an aryl group optionally having an alkyl group having 2 to 10 carbon atoms when Z is —S—.
