Abstract
Poly(amideimide)s were prepared by the reaction of two new AB monomers, N-(4-aminophenyl)-4-(p-carboxyphenoxy)phthalimide and N-(3-aminophenyl)-4-(p-carboxyphenoxy)phthalimide. The monomers were synthesized by nucleophilic displacement reaction of the corresponding nitrophthalimides with p-hydroxybenzoic acid. The monomers were characterized by IR and NMR. Poly(amideimide)s were prepared from AB monomers by direct polycondensation using triphenyl phosphite. The polymers obtained had high inherent viscosities. The polymers showed high solubility in polar aprotic solvents. The polymers showed good thermal stability and had high glass transition temperatures. X-ray diffraction pattern of the polymers indicate amorphous nature of these polymers.
