Fluorine-containing elastomer mixture, method for producing same, composition for vulcanizing peroxide, and molded article
摘要：
A fluoroelastomer mixture, including: a peroxide-vulcanizable fluoroelastomer (A) containing an iodine atom; and a peroxide-vulcanizable fluoroelastomer (B) containing an iodine atom. The fluoroelastomer (A) is a copolymer (a1) consisting of 50 to 85 mol % of a vinylidene fluoride unit and 15 to 50 mol % of a perfluoro(alkyl vinyl ether) unit, or a copolymer (a2) consisting of 45 to 85 mol % of a vinylidene fluoride unit, 1 to 30 mol % of a tetrafluoroethylene unit, and 14 to 30 mol % of a perfluoro(alkyl vinyl ether) unit. Further the fluoroelastomer (B) has a fluorine content of 70.0% or more. Also disclosed is a composition for peroxide vulcanization containing the above fluoroelastomer composition (i), a polyfunctional unsaturated compound (ii) and a peroxide (iii), as well as a method for producing the fluoroelastomer mixture.
摘要（中）：

一种含氟弹性体混合物，包括：含有碘原子的过氧化物可硫化的含氟弹性体（A） 和含有碘原子的过氧化物可硫化的含氟弹性体（B）。 含氟弹性体（A）是由50〜85摩尔％的偏氟乙烯单元和15〜50摩尔％的全氟（烷基乙烯基醚）单元组成的共聚物（a1），或由45〜85组成的共聚物（a2） 偏二氟乙烯单元的摩尔％，四氟乙烯单元为1〜30摩尔％，全氟（烷基乙烯基醚）单元为14〜30摩尔％。 此外，含氟弹性体（B）的氟含量为70.0％以上。 还公开了含有上述含氟弹性体组合物（i），多官能不饱和化合物（ⅱ）和过氧化物（ⅲ）的过氧化物硫化的组合物，以及含氟弹性体混合物的制造方法。
