    摘要: Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain hydrazide curatives. The hydrazide is of the general formula R1(C(O))nNHNHR2, wherein n is 1 or 2; R1 is NH2, NHNH2, NHR3, NR32, NHNHC(O)NH2, NHNHC(O)NHNH2, NHNHR2, or NHC(O)NHNH2; R2 is H, alkyl, aryl, heterocycle, CO2R3, C(O)R3, CH2R4, or C(O)R4; R3 is alkyl, aryl, heterocycle, or CH2R4; and R4 is a fluoroalkyl group.
