POLYMER CONTAINING SULFO GROUP AND ORGANIC ELECTROLUMINESCENT ELEMENT CONTAINING THE POLYMER

摘要

A polymer compound suitable for use in organic electroluminescent elements; a process for producing the compound; and an organic electroluminescent element employing the compound. 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): wherein, in the formula, Ar 1 and Ar 2 each represents a monovalent aromatic group; Y represents a divalent group comprising an aromatic group; and W represents a divalent aromatic group having 4 to 30 carbon atoms.
