摘要：
The one-pot high temperature catalytic polycyclocondensation of diamines and dianhydrides in molten benzoic acid (BA) was studied. Due to specific features of molten BA as a solvent, obtaining new random and alternating copolyimides (CPIs) becomes possible. Several series of CPIs containing the moieties of different diamines (para- and meta- aromatic, hinged aromatic, aliphatic C-6-C-12, cardo-, adamanthane containing) in different combinations to each other as well as corresponding homopolyimides were synthesized using one-, two-, or three-portions of comonomer loading. Polymers were characterized by means of viscosimetry, solubility evaluation, DSC and WAXD.
