摘要
综述了聚氨酯的热降解过程及产物,探讨了热降解条件、软段、NCO:OH摩尔比、异氰酸酯种类、扩链剂、交联度、杂环基团对聚氨酯耐热性能的影响,并对聚氨酯耐热性能改进方法进行了总结。
The process and products of thermal degradation of polyurethane were reviewed. The effects of thermal degradation conditions, soft segment, NCO：OH mole ratio, isocyanate species, chain extender, cross-linking degree and heterocyclic groups on the thermal stability of polyurethane were also discussed. Moreover, the method of improving thermal stability of polyurethane was summarized.
