摘　　要：采用自制钌系催化剂[1,3-双(三甲基苯基)-2-咪唑啉亚基]二氯(邻甲氧基苯亚甲基)合钌制备了氢化丁腈橡胶(HNBR)乳液,考察了催化剂的催化活性、对双键的选择性及所得HNBR的凝胶含量、硫化特性、物理机械性能、耐热空气老化和耐油性能。结果表明,该钌系催化剂可以选择性氢化丁腈橡胶分子链上的碳碳双键而保留氰基。当催化剂占丁腈橡胶的质量分数为0.05%时,反应3 h即可得到加氢度95%以上且不含凝胶的HNBR产品。在乳液状态下使用该催化剂制备的HNBR的各项性能与进口产品Therban 3406相当。The ruthenium-based catalyst[1,3-bis(trimethylphenyl)-2-imidazolinylidene]dichloro(o-methoxybenzylidene)ruthenium was synthesized and used to prepare the latex of hydrogenated nitrile rubber(HNBR).The selectivity and reactivity of catalyst,the gel content,curing characteristics,physical mechanical properties,hot air aging resistance and oil resistance of the HNBR had been stu-died in detail.The results showed that the ruthe-nium-based catalyst could selectively hydrogenate the carbon carbon double bond on the molecular chain of nitrile rubber and retain the cyano group.When the mass fraction of NBR was 0.05%,the HNBR product with more than 95%hydrogenation degree and without gel could be obtained after 3 h reaction.In addition,the performance of HNBR prepared in the emulsion state using the catalyst could be compared with commercial product Therban 3406.
