The present invention relates to a fluoropolymer comprising repeating units derived from one or more gaseous fluorinated olefins and having one or more cure sites comprising (a) a halogen capable of participating in a peroxide cure reaction or (b) a nitrile group, said fluoropolymer further comprising repeating units derived from one or more fluorinated allyl ethers of the formula: CF.sub.2.dbd.CF--CF(Z)--O--R.sub.f (I) wherein Z represents F or CF.sub.3 and R.sub.f represents a fluorinated alkyl group that may contain one or more catenary oxygen atoms. The fluoropolymer can be cured to a fluoroelastomer. The invention also relates to a curable fluoroelastomer composition comprising the fluoropolymer and a curing agent.
