    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)-NR 1 2 , -C≡N, -C(O)NR 1 -SO 2 -R f 1 -W, or a fluorinated alkenyl group that is optionally interrupted by one or more -O- groups. HAL is -F, -Cl, or -Br. R f 1 is a fluorinated alkylene group that is optionally interrupted by one or more -O- groups. W is -F, -SO 2 Z, -CF=CF 2 , -O-CF=CF 2 , or -O-CF 2 -CF=CF 2 . Z is -F, - Cl, -NR 1 2 , or -OM. Each R 1 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.
