To provide a curable polymer having high solvent resistance due to high crosslinkability, as an organic polymer material used in manufacture of an organic light emitting element, and also to provide a long-life and highly efficient organic light emitting element.SOLUTION: One embodiment of the present invention relates to a curable polymer including: a first polymer having a main chain including a linear conjugated monomer and a branched conjugated monomer as a repeating unit and a side chain including one or more crosslinking groups; and a second polymer having a main chain different from that of the first polymer and a side chain including one or more crosslinking groups. Another embodiment of the present invention relates also to a polymerization solution containing the curable polymer, a resin obtained by the polymerization of the curable polymer, and an organic light emitting element containing the resin in a hole transport layer.SELECTED DRAWING: Figure 1 【課題】本発明の一態様は、有機発光素子の製造に用いる有機高分子材料として、高い架橋性による高い耐溶媒特性を有する硬化性重合体を提供することを目的とする。また、本発明の別の一態様は、長寿命且つ高効率の有機発光素子を提供することを目的とする。【解決手段】本発明の一態様は、直鎖状共役モノマー及び分岐状共役モノマーを繰り返し単位として含む主鎖と、1個以上の架橋基を含む側鎖とを有する第一の高分子と、第一の高分子の主鎖とは異なる主鎖と、1個以上の架橋基を含む側鎖とを有する第二の高分子と、を有する硬化性重合体に関する。本発明の別の一態様は、前記硬化性重合体を含む重合液、前記硬化性重合体を重合して得られる樹脂、並びに前記樹脂を正孔輸送層に含む有機発光素子にも関する。【選択図】図１
