<P>PROBLEM TO BE SOLVED: To provide a new sulfonated triarylamine polymer soluble in water or alcohol, and having good conductivity and heat resistance. <P>SOLUTION: This sulfonated triarylamine polymer is obtained by oxidative reaction of a sulfonated triarylamine polymer represented by general formula (1), where in formula, Ar<SB POS="POST">1</SB>s each independently represents a 6-20C aromatic group which may have a substituent; Ar<SB POS="POST">2</SB>represents a sulfonated phenyl group which may have a substituent; m is an integer of 1 or more; X represents a hydrogen atom, alkali metal of Li, K or Na; and an amine salt represented by NH(R<SB POS="POST">4</SB>)<SB POS="POST">3</SB>; provided that R<SB POS="POST">4</SB>s each independently represents a hydrogen atom, an alkyl group or an aryl group which may have a substituent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
