A novel hydrazine-containing diamine 3,3'-bis(N-aminophthalimide) thioether was synthesized.Its structure was determined by means of 1H NMR and IR.Two polyimides were prepared with the diamine and dianhydrides 4,4'-HQDPA or BPADA via conventional one-step method in p-chlorophenol.These polymers show very good solubility in polar aprotic solvents and phenols at room temperature.The glass-transition temperatures of the polymers are 324 ℃ and 280 ℃,and the temperatures at which the mass loss is 5% are 486 ℃ and 466 ℃.
