英文摘要	An asymmetrical aromatic diamine, 1-(4'-aminophenoxy)-4-(4'-aminophenylenesulfanyl) benzene (OSDA) was synthesized. A series of polythioetherimides (PTEIs) were prepared from a thioether-bridged aromatic dianhydride 4,4'-[p-thiobis(phenylenesulfanyl)]diphthalic anhydride (3SDEA) and various aromatic diamines having ether or thioether linkages between phenylene rings by a two-step poly-condensation procedure via their soluble poly(amic acid) (PAA) precursors. Medium to high molecular weight PAAs were obtained with inherent viscosities near or higher than 1.0 dL g(-1), which is high enough to afford flexible and tough PTEI films except for PI-2 (3SDEA-134APB) and PI-6 (3SDEA-m2SPDA) derived from meta-ether-substituted diamines. PI-2 and PI-6 showed some extent of crystallinity compared to the amorphous natures of the other polymers. The PTEI films exhibit good resistance to organic solvents except for PI-3 (3SDEA-133APB), which is soluble in N-methyl-2-pyrrolidinone (NMP) and sulfuric acid at room temperature. The PTEI films show good thermal stability with the 5% weight loss temperatures being above 480 degrees C both in nitrogen and in air. The glass transition temperatures of the PTEIs are in the range of 155 - 191 degrees C, which are lower than those of the commercial polyetherimides due to their plural thioether linkages in the main chains.
