POLYMER CONTAINING SULFO GROUP AND ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING THE POLYMER

摘要

A polymer suitable for use in organic electroluminescent elements; a process for producing the polymer; and an organic electroluminescent element employing the polymer. The polymer is a sulfo-containing polymer characterized by having a structure formed by introducing sulfo groups into a polymer comprising repeating units represented by the general formula (1): (Chemical formula 1) (1) (wherein Ar1 and Ar2 each represents a monovalent aromatic group; Y represents a divalent group comprising an aromatic group; and W represents a C4-30 divalent aromatic group.)
