The present invention relates to a polyamideimide comprising an asymmetric dicarboxylic acid derivative wherein, from among a cyclic group A and a cyclic group B, two substitutents groups R and R′ are bonded only to the cyclic group A on one side. A polymer produced by means of the present invention can have adequate solubility with respect to organic solvents, high thermal stability, a high glass transition temperature, high transparency and a low thermal expansion coefficient, and is able not only to satisfy requirements for core substrate materials of flexible displays but also to be used as a material for various soft electronic data devices.
本发明涉及一种聚酰胺酰亚胺,其包括一种不对称二羧酸衍生物,其中,从环状基团A和环状基团B中选择,两个取代基R和R'仅在一侧与环状基团A相结合。通过本发明手段生产的聚合物可以在有机溶剂中具有足够的溶解性,具有高热稳定性,高玻璃化转变温度,高透明度和低热膨胀系数,并且不仅能够满足柔性显示器的核心基板材料的要求,还可以用作各种软性电子数据设备的材料。
