摘要
PROBLEM TO BE SOLVED: To provide improved curatives capable of more easily dispersing in and more quickly curing perfluoroelastomers, particularly cyano curable perfluoroelastomers.;SOLUTION: 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.;COPYRIGHT: (C)2014,JPO&INPIT
