Fluoropolymer for making a fluoroelastomer
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（中）：

本发明涉及包含衍生自一种或多种气态氟化烯烃并具有一个或多个固化位点的重复单元的含氟聚合物，其包含（a）能够参与过氧化物固化反应的卤素或（b）腈基，所述含氟聚合物进一步 包含衍生自下式的一种或多种氟化烯丙基醚的重复单元：<？in-line-formula description =“In-line Formulas”end =“lead”？> CF2-CF-CF（Z）-O-Rf（ I）<？in-line-formula description =“In-line Formulas”end =“tail”？>其中Z表示F或CF 3，Rf表示可含有一个或多个链状氧原子的氟化烷基。 氟聚合物可以固化成含氟弹性体。 本发明还涉及含氟聚合物和固化剂的可固化含氟弹性体组合物。
