Notes:
Polycondensation of bis-N-hydroxyimides, N,N′ dihydroxypyromellitic diimide, and N,N′ -dihydroxybenzophenonetetracarboxylic diimide with dicarboxylic acid chlorides was carried out in dimethylacetamide in the presence of triethylamine to produce novel polyimide-esters. The resulting polymers had inherent viscosities up to 0.27 dl/g. These polyimide-esters and model compounds exhibited high reactivity toward nucleophiles such as aniline and n-butylamine, which brought about rapid reductions in the viscosity of the polymers. These polymers were fairly resistant to organic solvents but soluble in m-cresol. Thermal stability oft he polyimide-esters was evaluated by thermogravimetry and their good heat-resistant properties were confirmed.
