摘　　要：研究端羟基液体氟26橡胶的制备与应用。用硼氢化钾/稀硫酸体系作催化剂对端羧基液体氟26橡胶进行还原制得遥爪聚合物端羟基液体氟26橡胶。分别以端羟基液体氟26橡胶和端羧基液体氟26橡胶作为增塑剂制备氢化丁腈橡胶(HNBR)胶料。结果表明,2种液体氟26橡胶与HNBR的相容性好,加入端羟基液体氟26橡胶的胶料物理性能、耐老化性能以及耐ASTM 1#油性能较好。In this study,the hydroxyl terminated liquid fl uororubber 26 was prepared and its application was investigated. The hydroxyl terminated rubber was prepared by reduction reaction of carboxyl terminated precedent investigated. The hydroxyl terminated rubber was prepared by reduction reaction of carboxyl terminated precedent using potassium borohydride/sulfuric acid as catalyst system. The hydroxyl terminated fl uororubber 26 and carboxyl terminated fluororubber 26 were then applied in HNBR as plasticizers,respectively. It was found both liquid fl uororubbers showed good compatibility with HNBR. The physical properties,aging resistance and resistance to ASTM 1# oil of the HNBR vulcanizates with hydroxyl terminated liquid fl uororubber 26 were better. oil of the HNBR vulcanizates with hydroxyl terminated liquid uororubber 26 were better.
