Abstract:
A peroxide-crosslinkable fluoroelastomer obtained by copolymerizing 0.1-20 mol% fluoroolefin iodide mixture represented by the general formula CnF2n+1CF2CH=CF(CF2CF2)mI [Ia] and general formula CnF2n+1CF=CHCF2(CF2CF2)mI [Ib] (wherein n is an integer of 0-5 and m is an integer of 1-3).  This peroxide-crosslinkable fluoroelastomer is a fluoroelastomer having side chains formed by copolymerizing monomers having a halogen atom capable of crosslinking with a peroxide.  When crosslinked with a peroxide, the fluoroelastomer gives a vulcanizate which has excellent material properties and can have improved compression set characteristics.
