Synthetic Route of 652-12-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.652-12-0, Name is Tetrafluorophthalic anhydride, molecular formula is C8F4O3. In a Article，once mentioned of 652-12-0
Novel highly fluorinated polyimides containing hexafluoronaphthylene fragment in the main chain were prepared by the two-stage polymerization of 2,7- and 2,6-diaminohexafluoronaphthalenes with 4,4?-oxydiphthalic anhydride: polycondensation in a solution at 80 C followed by high-temperature solid-state chain extension. The influence of hexafluoronaphthylene fragment isomerism on the key polyimide features – molecular weight, thermal stability, solubility, optical properties – was characterized. Polyimides based on 2,7-diaminohexafluoronaphthalene or easily accessible mixture of isomeric diamines formed the flexible, transparent, and thermostable films.
