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).
本发明提供了:一种具有高孔注入/传输能力的高耐久性聚合物;以及一种含有该聚合物的有机电致发光元件组合物。该聚合物含有下式(1)代表的重复单元或下式(2)代表的重复单元(其中,Ar1 和 Ar2 各自代表可选具有取代基的芳香烃基团,或可选具有取代基的芳香杂环基团;X 代表-C(R7)(R8)-、-N(R9)-或-C(R11)(R12)-C(R13)(R14)-;R1 和 R2 以及 R3 和 R6 各自独立地代表可选具有取代基的烷基;R4 和 R5 各自独立地代表任选具有取代基的烷基、任选具有取代基的烷氧基或任选具有取代基的芳烷基;以及 R7 至 R9 和 R11 至 R14 各自独立地代表氢、任选具有取代基的烷基、任选具有取代基的芳烷基或任选具有取代基的芳香烃基。)
