Polyamides represent one class of materials that is important in modern society. Because of the numerous potential applications of polyamides in various fields, there is a high demand for new polyamide structures, which necessitates the development of new polymerization methods. Herein, we report a novel and efficient palladium-catalyzed hydroaminocarbonylative polymerization of dienes and diamines for the synthesis of cycloaliphatic polyamides. The method employs readily available starting materials, proceeds in an atom-economic manner, and creates a series of new functional polyamides in high yields and high molecular weights. In contrast with the traditional polyamides based on adipic acid, the cycloaliphatic polyamides have superior thermal resistance, higher glass-transition temperature, and better solubility in common organic solvents, thus probably featuring the merits of high-performance and good processability.
聚酰胺是现代社会中一类重要的材料。由于聚酰胺在各个领域有众多潜在应用，对新型聚酰胺结构有很高的需求，这就需要开发新的聚合方法。在此，我们报道了一种新颖且高效的钯催化二烯和二胺的氢胺羰基化聚合反应，用于合成脂环族聚酰胺。该方法使用易得的起始原料，以原子经济的方式进行，并能高产率、高分子量地制备一系列新型功能性聚酰胺。与基于己二酸的传统聚酰胺相比，脂环族聚酰胺具有优异的耐热性、更高的玻璃化转变温度以及在常见有机溶剂中更好的溶解性，因此可能具有高性能和良好加工性能的优点。
