  摘要：

  提供具有低薄膜颜色、原子氧抗性、真空紫外辐射抗性、酰亚胺形式下有机溶剂溶解性、高玻璃化转变温度（Tg）和高热稳定性的聚酰亚胺。通过在极性无水溶剂中使用含有苯基膦氧基团的二胺与芳香族二酸酐的化学计量比反应，制备聚酰胺酸、共聚酰胺酸、聚酰亚胺和共聚酰亚胺。通过使用过量二胺和芳香族酸酐进行端基封闭，可以根据Carothers方程抵消化学计量比，制备控制分子量的寡聚物酰胺酸和酰亚胺。这些聚酰亚胺材料可以加工成各种形式，如薄膜、纤维、泡沫、线、粘合膜、涂层、干粉和纤维涂层预浸料，用途包括天线上的薄膜膜、第二面镜、热光学涂层和多层热隔热毯材料。

  Polyimides displaying low color in thin films, atomic oxygen resistance, vacuum ultraviolet radiation resistance, solubility in organic solvents in the imide form, high glass transistion (T g ) temperatures, and high thermal stability are provided. The poly(amide acid)s, copoly(amide acid)s, polyimides and copolyimides are prepared by the reaction of stoichiometric ratios of an aromatic dianhydride with diamines which contain phenylphosphine oxide groups in polar aprotic solvents. Controlled molecular weight oligomeric (amide acid)s and imides can be prepared by offsetting the stoichiometry according to the Carothers equation using excess diamine and endcapping with aromatic anhydrides The polyimide materials can be processed into various material forms such as thin films, fibers, foams, threads, adhesive film, coatings, dry powders, and fiber coated prepreg, and uses include thin film membranes on antennas, second-surface mirrors, thermal optical coatings, and multi-layer thermal insulation (MLI) blanket materials.
