聚硫醚橡胶仅含有单硫键,比传统聚硫橡胶的双硫键键能更高,因此耐热性更佳,其在航空油箱密封剂领域的应用逐渐扩大。综述了近年来国内外关于聚硫醚橡胶的研究现状,主要关于聚硫醚的合成路线及多种官能团封端,以及聚硫醚制备成密封剂的性能的研究。
Comparing with traditional polysulfide with double-sulfur bond,polythioether with single-sulfur bond has better thermal resistance,so it has gradually been applied in air craft fuel tank field.Recent developments of synthesis of polythioether and derivatives were summarized.The application of polythioether rubber in sealant materials was also introduced.
