PROBLEM TO BE SOLVED: To provide a curable composition of an amorphous, peroxide-curable fluoropolymer and a solvent, useful, for example, for making cured fluoroelastomers.SOLUTION: This invention relates to a curable composition, comprising an amorphous, peroxide-curable fluoropolymer having a first solubility parameter, a solvent having a second solubility parameter, and a peroxide. The amorphous, peroxide-curable fluoropolymer is present from 60 percent to 97.5 percent by weight versus the weight of the curable composition, and the solvent is present from 1 percent to 39 percent by weight versus the weight of the curable composition. The absolute value of the first solubility parameter minus the second solubility parameter is less than or equal to 8.2 (MPa). The solvent may have a solubility parameter in a range from 9.6 (MPa)to 26 (MPa). Methods of making a cured fluoroelastomer from the curable composition are also disclosed.SELECTED DRAWING: None 【課題】硬化フルオロエラストマーを作製するのに有用な、非晶質ペルオキシド硬化性フルオロポリマー及び溶媒の硬化性組成物を提供する。【解決手段】第１の溶解度パラメータを有する非晶質ペルオキシド硬化性フルオロポリマーと、第２の溶解度パラメータを有する溶媒と、ペルオキシドと、を含む、硬化性組成物。非晶質ペルオキシド硬化性フルオロポリマーは、硬化性組成物の重量に対して６０重量パーセント〜９７．５重量パーセント存在し、溶媒は、硬化性組成物の重量に対して１重量パーセント〜３９重量パーセント存在する。第１の溶解度パラメータから第２の溶解度パラメータを引いた絶対値は、８．２（ＭＰａ）１／２以下である。溶媒は、９．６（ＭＰａ）１／２〜２６（ＭＰａ）１／２の範囲の溶解度パラメータを有し得る。また、硬化性組成物から硬化フルオロエラストマーを作製する方法についても開示する。【選択図】なし
