Abstract
New poly(benzimidazole-imide-amide)s containing hexafluoroisopropylide ne units in the backbone have been synthesized by polycondensation of diaminobenzimidazoles with novel diacid dichlorides which incorporated both imide and hexafluoroisopropylidene groups. These polymers have h igh thermal stability and low dielectric constant and are soluble in p olar aprotic solvents giving transparent, flexible films by casting th eir solutions. Such properties make them attractive for applications a s dielectric coatings in microelectronics.
