Abstract

See full text

Provided are: a highly durable polymer having a high hole-injection/transport capacity; and a composition for an organic electroluminescent element, which contains the polymer. The polymer contains a repeating unit represented by the following Formula (1) or a repeating unit represented by the following Formula (2) (wherein, Ar1 and Ar2 each represent an aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent; X represents —C(R7)(R8)—, —N(R9)—, or —C(R11)(R12)—C(R13)(R14)—; R1 and R2 as well as R3 and R6 each independently represent an alkyl group optionally having a substituent; R4 and R5 each independently represent an alkyl group optionally having a substituent, an alkoxy group optionally having a substituent, or an aralkyl group optionally having a substituent; and R7 to R9 and R11 to R14 each independently represent hydrogen, an alkyl group optionally having a substituent, an aralkyl group optionally having a substituent, or an aromatic hydrocarbon group optionally having a substituent).
