中文摘要 | a facile method for the synthesis of biphenyl polyimides, which involves the nickel-catalyzed coupling of aromatic dichlorides containing imide structure in the presence of zinc and triphenylphosphine, has been developed. the polymerizations proceeded smoothly under mild conditions and produced biphenyl polyimides with inherent viscosities of 0.13-0.98 dl/g. the polymerizations of bis(4-chlorophthalimide)s with bulky side substituents gave high molecular weight polymers. low molecular weight polymers from bis(4-chlorophthalimide)s containing rigid diamine moieties and bis(3-chlorophthalimide)s were obtained because of the formations of polymer precipitate and cyclic oligoimides, respectively. the effects of various factors, such as amount of catalyst, solvent volume, ligand, reaction temperature, and time, on the polymerization were studied. the random copolymerization of two bis(chlorophthalimide)s in varying proportions produced medium molecular weight material. the tgs of prepared polyimides were observed at 245-311 degreesc, and the thermogravimetry of polymers showed 10% weight loss in nitrogen at 470-530 degreesc. |
