A new series of five thermally and dimensionally stable aromatic poly(ether-imide)s consisting of an electron donating ortho-catenated triphenylamine (TPA) derivative bearing two trifluoromethyl groups and various electron-accepting phthalimide moieties were synthesized and thoroughly investigated. These polyimides display excellent organosolubility, unexpectedly even in ethanol, which allows their...
A thorough study on the physico-chemical properties of novel blends of fluorinated aromatic polyimides prepared on the basis of the similarity of dianhydride monomer units was performed. High-temperature solution polycondensation reactions resulted in high molecular weights polyimides further used as blend components. The blend films and coatings were rootedly characterized by various methods, including...
This study focuses on the synthesis and characterization of new polyimide films with ortho-kink structures based on trifluoromethyl-containing diamines and hexafluoroisopropylidene-containing dianhydrides. High-temperature solution polycondensation reactions via conventional two-stage process involving the thermal imidization of the poly(amic acid) precursors resulted in polyimides with high molecular...
