    Abstract: The multifunctional compound is represented by formula X—C(R)RF—Y, in which X and Y are each independently —C(O)—O-M, —C(O)-HAL, —C(O)—NR12, —C≡N, —C(O)NR1—SO2—Rf1-W, or a fluorinated alkenyl group that is optionally interrupted by one or more —O— groups. HAL is —F, —Cl, or —Br. Rf1 is a fluorinated alkylene group that is optionally interrupted by one or more —O— groups. W is —F, —SO2Z, —CF═CF2, —O—CF═CF2, or —O—CF2—CF═CF2. Z is —F, —Cl, —NR12, or —OM. Each R1 is a hydrogen atom or alkyl having up to four carbon atoms. M is an alkyl group, a trimethylsilyl group, a hydrogen atom, a metallic cation, or a quaternary ammonium cation. R is a bromine, chloride, fluorine or hydrogen atom; and RF is a fluorinated alkenyl group that is unsubstituted or substituted by at least one chlorine atom, aryl group, or a combination thereof or RF is a fluorinated alkyl group or arylalkylenyl group that is substituted by bromine or iodine and uninterrupted or interrupted by at least one —O— group. A process for making the compound is also disclosed. A fluoropolymer made from the compound and a method of making the fluoropolymer are also disclosed.
