Abstract
Disclosed is a peroxide-crosslinkable fluoroelastomer obtained by copolymerization of 0.1 to 20 mol % of a mixture of fluoroolefin iodides represented by the general formulae: CnF2n+1CF2CH═CF(CF2CF2)mI [Ia] and CnF2n+1CF═CHCF2(CF2CF2)mI [Ib], wherein n is an integer of 0 to 5, and m is an integer of 1 to 3. The peroxide-crosslinkable fluoroelastomer is copolymerized with a monomer having a side chain containing a peroxide-crosslinkable halogen atom, and has excellent vulcanizate physical properties and improved compression set characteristics when subjected to peroxide crosslinking.
