Described herein is the curing of a fluorinated elastomeric gum with peroxide and a co-agent of Formula I or salt thereof, wherein Formula I is (CH2=CHCH2)2-L1-Rf-L2-(CH2CH=CH2)n(H)2-n wherein L1 is -NSO2- or -NCO-; L2 is -SO2N- or -CON-; n is 1 or 2; and Rf is a divalent perfluorinated carbon group, optionally comprising at least one ether linkage; and cured articles therefrom. 本文描述了利用过氧化物和式I的助剂或其盐的氟化弹性体胶的固化，其中式I为(CH＝CHCH)-L-Rf-L-(CHCH＝CH)(H)，其中L为-NSO-或-NCO-；L为-SON-或-CON-；n为1或2；并且Rf为二价全氟化碳基团，其任选地包含至少一个醚键。以及由其制得的固化制品。
