Title:
DIAMINE COMPOUND AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/038436
Kind Code:
A1
Abstract:
The present invention provides a novel diamine compound capable of producing a polymer which exhibits greatly enhanced mechanical properties and heat resistance while maintaining transparency. A film including a polymer produced using the diamine compound has excellent transparency, heat resistance, mechanical strength, and flexibility, and thus can be used in various fields, such as in a device substrate, a display cover substrate, an optical film, an integrated circuit (IC) package, an adhesive film, a multilayer flexible printed circuit (FPC), a tape, a touch panel, an optical disc protection film, and the like.
