## Abstract We prepared poly(__p__‐phenylene pyromellitimide) (PMDA–PDA), poly(__p__‐phenylene 4,4′‐hexafluoroisopropylidene diphthalimide), and their copolyimides with various compositions to explore the relationship between the water sorption and structure. The water sorption behaviors were gravi
