聚氨酯橡胶扩链剂──醇胺类化合物

CHAIN EXTENDERS─ALCOHOLAMINES FOR POLYURETHANE RUBBERS

主要论述了作为聚氨酯（ＰＵ）橡胶扩链剂的醇胺及其衍生物的品种、分类、结构、性质、制备方法和扩链反应原理，以及在浇注型ＰＵ橡胶中的使用效果等。在ＰＵ合成中，这种扩链剂与相应胺类扩链剂相比，大部分具有良好的工艺性能，所得ＰＵ材料与相应的多元醇相比，又具有良好的力学性能和其他性能。

This is a review with 18 references on the chain extenders,alcoholamines and their derivatives for polyurethane rubbersl deals with variety,classification,effect different structure,properties,prepa-ration methods,extending reaction mechanism,and application.Most of these extenders affords more pot life in the casting course comparing with corresponding diamines,and provides these rubbers with better mechanical and other properties comparing with corresponding glycols.
