Zusammenfassung: | The present invention provides a polymer composition capable of obtaining a cured film having little generation of out gas and excellent heat resistance, the cured film and an organic electroluminescent (EL) element. The present invention provides the polymer composition, which includes a polymer component (A), a reaction initiator (B), and a polyfunctional polymerizable compound (C), and the polymer component (A) includes a structural unit (Uα) derived from at least one selected from the group consisting of an N-substituted maleimide compound having a monovalent cyclic hydrocarbon group and a (meth)acrylic compound having a monovalent cyclic hydrocarbon group. The structural unit (Uα) contains a structural unit (U1) derived from an N-substituted maleimide compound having a monovalent cyclic hydrocarbon group in an amount of 28 mass% or more based on the total amount of the structural unit (Uα) contained in the polymer component (A).
