<P>PROBLEM TO BE SOLVED: To provide a method for producing an aromatic polymer with high molecular weight. <P>SOLUTION: The method for producing the aromatic polymer includes a step to mix an aromatic monomer represented by formula (A): X<SP POS="POST">1</SP>-Ar<SP POS="POST">1</SP>-X<SP POS="POST">1</SP>(A) (in formula, X<SP POS="POST">1</SP>represents a group represented by any one of formulas (1) to (6), and Ar<SP POS="POST">1</SP>represents a divalent aromatic hydrocarbon group) and an aromatic monomer represented by formula (B): X<SP POS="POST">2</SP>-Ar<SP POS="POST">2</SP>-X<SP POS="POST">2</SP>(B) (in formula, X<SP POS="POST">2</SP>represents a chlorine atom etc., and Ar<SP POS="POST">2</SP>represents a divalent aromatic hydrocarbon group) in the presence of a base, a palladium compound, a specified phosphine, and an aprotic organic solvent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
