Thermostable poly(amide-imide)s containing para-meta benzoic structure were synthesized by reacting a para-meta benzoic polyamide prepolymer with various diisocyanate-terminated polyimide prepolymers. The polyamide prepolymers were prepared by first reacting m-phenylene diamine and isophthaloyl dich
