Solution Polycondensation

New poly(phenylquinoxaline-amide)s and poly(phenylquinoxaline-imide-amide)s containing pendent phthalimide or 3,4,5,6-tctrachlorphthalimide groups have been synthesized by low-temperature solution polycondensation of diaminophenylquinoxalines with diacid chlorides of two aromatic acids containing preformed imide ridgs. The inherent viscosity, solubility, thermal stability, glass transition tempratures, dielectric constants and mechanical properties of these polymers have been studied.
