Synthesis and study of new fluorinated poly(imide-amide)s

摘要: New fluorinated poly(imide-amide)s have been synthesized by solution polycondensation of various aromatic diamines containing a natphthalene unit with diacid (6F) groups. These polymers are soluble in polar aprotic solvents, such as N-methylpyrrolidone (NMP) or N,N-dimethylformamide (DMF), and can be cast into flexible thin films from solutions. They show high thermooxidative stability decomposition temperatures being the range 235-305°C. The polymer exhibit low dielectric constant tough mechanical properties.
