| 中文摘要 | 2-(4-aminophenyl)-5-aminopyrimidine (4) is synthesized via a condensation reaction of vinamidium salts and amidine chloride salts, followed by hydrazine palladium catalyzed reduction. a series of novel homo- and copolyimides containing pyrimidine unit are prepared from the diamine and 1,4-phenylenediamine (pda) with pyromellitic dianhydride (pmda) or 3,3',4,4'-biphenyl tertracarboxylic dianhydride (bpda) via a conventional two-step thermal imidization method. the poly(amic acid) precursors had inherent viscosities of 0.97-4.38 dl/g (c = 0.5 g/dl, in dmac, 30 degrees c) and all of them could be cast and thermally converted into flexible and tough polyimide films. all of the polyimides showed excellent thermal stability and mechanical properties. the glass transition temperatures of the resulting polyimides are in the range of 307-434 degrees c and the 10% weight loss temperature is in the range of 556-609 degrees c under air. the polyimide films possess strength at break in the range of 185-271 mpa, elongations at break in the range of 6.8-51%, and tensile modulus in the range of 3.5-6.46 gpa. the polymer films are insoluble in common organic solvents, exhibiting high chemical resistance. |
