摘要
针对聚氨酯（ＰＵ）耐热性能较差的问题，简述了ＰＵ的结构与耐热性能的关系，及在ＰＵ中引入硅二醇、杂环基、扩链剂、异氰酸酯种类对耐热性能的影响。
The relationship between the structure and the heat resistance,the influence of varinous chain extenders and isocyanates on heat resistance,and the introduction of silicon-containing glycols and heterocyclic groups onto the main chains for increasing the heat resistance of polyurethane elastomers were reviewed with 5 references.
