    摘要: 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: CF2═CF—CF(Z)—O—Rf  (I) wherein Z represents F or CF3 and Rf 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.

    摘要: The present invention provides a method of recovering a fluorinated acid surfactant or salt thereof from adsorbent particles to which said fluorinated acid surfactant has been adsorbed. The method comprises mixing adsorbent particles having adsorbed fluorinated acid surfactant or salt thereof with an alcohol and optionally an acid. The mixture is generally heated to cause esterification of the fluorinated acid surfactant or salt thereof with the alcohol so as to form an ester derivative of the fluorinated acid surfactant, distilling the mixture to form a distillate comprising the ester derivative, separating the ester derivative from the distillate and optionally feeding the remainder of the distillate back into the mixture.
