    摘要: Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain carbazates. The carbazate is of the general formula R1OC(O)NHNHR2, wherein R1 is 9-fluorenylmethyl, benzyl, aryl, or a heterocycle; R2 is H, alkyl, aryl, heterocycle, CO2R3 or CH2R4; R3 is alkyl, aryl, benzyl or a heterocycle; and R4 is a fluoroalkyl group.
