| 摘要 |
This invention discloses new polybenzimidazolone polymers produced by the reaction of a hexafluoro aromatic tetraamine with a dianhydride reactant. These hexafluoro polybenzimidazolone polymers based on an aromatic hexafluoro tetraamine show improved solubility, easy processability, low moisture uptake, high thermal stability, resistance to solvent and other improvements over conventional polybenzimidazolone polymers.
