| 摘 要： | 采用含硫二胺1,4-双(4-氨基苯硫基)苯(2SPDA)与偏苯三酸酐反应制备了一种含硫二酸化合物1,4-双(4-三甲酰亚胺基苯硫基)苯(BTPB).以此二酸为原料与两种高硫含量二胺单体,4,4′-双(4-氨基苯硫基)二苯硫醚(3SDA)以及2,7-双(4-氨基苯硫基)噻蒽(APTT)通过高温缩聚法制备了两种聚酰胺酰亚胺(PAI).制备的PAI在室温下可溶解于N-甲基-2-吡咯烷酮(NMP)中.PAI薄膜的起始热分解温度(T5%)超过440℃,玻璃化转变温度(Tg)大于190℃.PAI薄膜在波长大于500nm的可见光区具有良好的透明性.此外,PAI薄膜的折射率大于1.73,双折射小于0.04.

| Abstract: | A series of novel poly(amide-imide)s(PAIs)containing sulfur elements were synthesized and characterized.The flexible sulfur-containing groups,either the linear thioether linkage or cyclic thianthrene group were introduced into the PAIs in order to increase the refractive indices and decrease birefringences of the polymers.Thus,an aromatic diacid compound 1,4-bis(4-trimellit-imidophenylenesulfanyl)benzene(BTPB)was first synthesized from a sulfur-containing diamine 1,4-bis(4-aminophenylenesulfanyl)benzene(2SP... |
