摘　　要：对改善推进剂工艺性能的文献进行了综述,包括对异氰酸酯改性、固化催化体系、工艺助剂和添加螯合剂的研究等,建议以三苯基铋延迟快速固化催化体系为基础,综合各种延长适用期、改善工艺性能的方法,解决二聚酸二异氰酸酯(DDI)在实际应用中的问题,推动DDI的实用化进程。The literatures about improving the processing performance of propellant are reviewed. The improving research includes the modification of isocyanate, curing catalytic systems, processing auxiliaries, the addition of che- lating agents and so on. It is suggested that based on using triphenyl bismuth to delay quick curing catalytic system, various methods for prolonging the pot life and improving the processing performance are combined to solve the prob- lems of dimer acid diisocyanate （DDI） in the actual applications and promote the practical process of DDI.
