  摘要：

  工业上重要的亚磷酸三芳基酯，传统上由 PCl 3制备，已通过涉及白磷和苯酚的二苯基二硒化物催化一步法合成，这为这些化合物提供了一种不含卤素和过渡金属的方法。随后亚磷酸三芳基酯氧化产生磷酸三芳基酯和硫代磷酸三芳基酯。三硫代磷酸酯也可以由芳香族硫醇和脂肪族硫醇有效地制备。

  This invention describes resins with phosphate cores and a simple, three-step process for their synthesis. Preferred resins are cyanate ester resins with bridging phosphate groups. These resins can be cured to produce thermoset polymers having Tgs of between 131 and >360° C. depending on the number of cyanate ester groups per phosphate and the substitution pattern of the aromatic rings. The high char yields of these resins, up to about 67%, coupled with the phosphate core means that these materials will have applications as fire-resistant polymers. Additionally, these materials can potentially be blended with conventional cyanate esters or other compatible thermosetting resins to improve the fire resistance of composite materials. Other applications may include use in fire-resistant circuit boards, or as surface coatings to reduce flammability of conventional composite materials or thermoplastics.

  这项发明描述了具有磷酸酯核心的树脂以及它们的合成的简单三步骤过程。首选的树脂是带有桥式磷酸酯基团的氰酸酯树脂。这些树脂可以固化成具有介于131°C和>360°C之间的玻璃化转变温度(Tg)的热固性聚合物，具体取决于每个磷酸酯基团的氰酸酯数量以及芳香环的取代模式。这些树脂的高碳烟产率高达约67%，再加上磷酸酯核心，意味着这些材料将应用于阻燃聚合物。此外，这些材料可能与传统氰酸酯或其他兼容的热固性树脂混合，以提高复合材料的防火性能。其他应用可能包括在阻燃电路板中使用，或作为表面涂层以降低传统复合材料或热塑性材料的易燃性。

  A method for the production of mechanically stabilized polyazole polymers, comprising the following steps: a) providing a membrane comprising i.) polyazoles with at least one amino group in a repeating unit except the ones obtainable by reacting aromatic and/or heteroaromatic diaminocarboxylic acids, ii.) at least one strong acid and iii.) at least one stabilizing reagent, the total content of stabilizing reagents in the membrane being within the range of from 0.01 to 30% by weight, b) performing the stabilization reaction in the membrane, immediately or in a subsequent processing step of the membrane, c) if appropriate, additionally doping the membrane obtained in accordance with step b) with a strong acid or concentrating the present strong acid further by removal of present water, wherein the stabilizing agent comprises at least one oxazine-based compound. The polyazole polymer membranes thus obtainable are in particular characterized by a high conductivity and a very good mechanical stability. Therefore, they are in particular suited for applications in fuel cells.
