Abstract

A cross-linkable, fluorine-containing elastomer composition comprising a fluorine-containing elastomer containing at least one of iodine and bromine in the molecule, an organic peroxide having a peroxy group --O--O--C(CH.sub.3).sub.2 R, where R is a lower alkyl group, in the molecule and an activation energy of not more than 34.0 Kcal/mole and another organic peroxide having the same peroxy group as defined above in the molecule and an activation energy of less than 34.0 Kcal/mole as cross-linking agents for the elastomer has less generation of CH.sub.3 I or CH.sub.3 Br at the decomposition of the organic peroxides without any substantial decrease in the compression set of the vulcanization products.
