The polysulfone has a good optical and thermal property. But it reveals poor chemical resistance in organic solvent such as NMP, DMAc. We introduced cross‐linkable imide moiety for the modification of polysulfone which could be overcome above shortcoming for display substrate based on plastic film. The cross‐linked polysulfone with imide chain had low CTE decreasing to 15% and the glass transition temperature (Tg) increasing to 252 °C.
