Abstract
Official abstract text for this publication.
The present invention relates to a method for manufacturing a polyarylene sulfide resin comprising: a step of reacting a poly(arylenesulfonium salt) having a constitutional unit represented by the following formula (1) with an aliphatic amide compound to obtain a polyarylene sulfide resin having a constitutional unit represented by the following formula (2): wherein R 1 represents a direct bond, —Ar 2 —, —Ar 2 —S— or —Ar 2 —O—; Ar 1 and Ar 2 each represent an arylene group optionally having a functional group as a substituent; R 2 represents an alkyl group having 1 to 10 carbon atoms or an aromatic group optionally having an alkyl group having 1 to 10 carbon atoms as a substituent; and X − represents an anion, wherein R 1 and Ar 1 are the same as described above.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a polyarylene sulfide resin comprising: reacting a poly(arylenesulfonium salt) having a constitutional unit represented by the following formula (1) with an aliphatic amide compound to obtain a polyarylene sulfide resin having a constitutional unit represented by the following formula (2): wherein R 1 represents a direct bond, —Ar 2 —, —Ar 2 —S— or —Ar 2 —O—; Ar 1 and Ar 2 each represent an arylene group optionally having a functional group as a substituent; R 2 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; and X − represents an anion, wherein R 1 represents a direct bond, —Ar 2 —, —Ar 2 —S— or —Ar 2 —O—; and Ar 1 and Ar 2 each represent an arylene group optionally having a functional group as a substituent. 2. The method for manufacturing a polyarylene sulfide resin according to claim 1 , wherein the aliphatic amide compound comprises an aliphatic tertiary amide compound.
