<P>PROBLEM TO BE SOLVED: To provide a new monomer having a sulfonic acid group, which is suitable as a monomer for forming a polymer to which ionic conductivity is imparted, and the polymer obtained by polymerizing the monomer. <P>SOLUTION: The biphenyltetrasulfonic acid compound is a compound represented by formula (1) (wherein R<SP>1</SP>s each independently represents a hydrogen atom, cation or 1-20C hydrocarbon group optionally having a substituent; R<SP>2</SP>s each independently represents a hydrogen atom, 1-20C alkyl group optionally having a substituent, 1-20C alkoxy group optionally having a substituent, 6-20C aryl group optionally having a substituent, 6-20C aryloxy group optionally having a substituent, 7-20C aralkyl group optionally having a substituent or 7-20C aralkyloxy group optionally having a substituent; and X<SP>1</SP>s each independently represents a chlorine atom, bromine atom or iodine atom). The polymer contains a structural unit originating in the biphenyltetrasulfonic acid compound represented by formula (1). <P>COPYRIGHT: (C)2011,JPO&INPIT |
