The present invention provides a method that can be prepared with greatly improved mechanical properties and heat resistance.nA novel diamine compound of a high molecular polymer that maintains transparency. The invention further provides a high molecular polymer composition, a high molecular polymer and a preparation method thereof, a transparent film and a display device. The film including the high molecular polymer prepared from the above-mentioned diamine compound has excellent transparency, heat resistance, mechanical strength, and flexibility, and thus can be used for, for example, a substrate for an element, a cover substrate for a display, an optical film, and a package circuit. Substrates, adhesive films, multilayer flexible printed circuits, tapes, touch panels, and protective films for optical discs. |
