<P>PROBLEM TO BE SOLVED: To provide a method for producing a new sulfonated triarylamine polymer easily dissolvable in water and alcohol through a few steps by using inexpensive raw materials stably industrially available. <P>SOLUTION: A sulfonating agent is reacted with a triarylamine polymer expressed by formula (7) in a basic polar solvent, where in formula, Ar<SB POS="POST">1</SB>represents a 6-20C aromatic group which may have a substitutent; m is an integer of 1 or more; Ar<SB POS="POST">5</SB>represents a benzene ring optionally including a substituent selected from a halogen atom, alkyl, alkoxy, alkenyl, aryl, arylamine or heteroaryl group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
