The feasibility of using a one-step high-temperature polycondensation for the synthesis of aromatic polyimides, based on 4,4'-diaminotriphenylmethane (DA-TPM), was studied. It was found that the reaction of DA-TPM with various aromatic dianhydrides in nitrobenzene at 180-200°C resulted in the format
