Novel monoamidine, monoamidoxime and bisamidine curatives, co-curatives and cure accelerators are provided for use with perfluoroelastomeric compositions as well as novel synthesis methods for making monoamidine- and monoamidoxime-based curatives, co-curatives and cure accelerators. Also provided are diphenyl-based curatives, co-curatives and cure accelerators having sufficiently high molecular weight such that the melting temperature of the curatives, co-curatives and cure accelerators is no greater than about 240° C., and more preferably no greater than about 230° C.
本发明提供了用于与全氟弹性体组合物一起使用的新型单氨基咪唑、单氨基肟和双咪唑治疗剂、共同治疗剂和治疗加速剂,以及用于制备基于单氨基咪唑和单氨基肟的治疗剂、共同治疗剂和治疗加速剂的新型合成方法。还提供了二苯基基治疗剂、共同治疗剂和治疗加速剂,其分子量足够高,使得治疗剂、共同治疗剂和治疗加速剂的熔点不大于约240℃,更好地不大于约230℃。
