PARTIALLY FLUORINATED SULFINIC ACID MONOMERS AND THEIR SALTS

Described herein is a composition according to formula I or its precursor, formula II: CX1X3=CX2-(R1)p-CZ1 Z2-SO2M (I) wherein X1, X2, and X3 are independently selected from H, F, Cl, Br, I, CF3 and CH3, and wherein at least one of X1, X2, or X3 is a H; R1 is a linking group; Z1 and Z2 are independently selected from F, Cl, Br, I, CF3, and a perfluoroalkyl group; p is 0 or 1; and M is a cation; and CX4X1X3-CX5X2-(R1)p-CZ1Z2-SO2M (II) wherein X1, X2, and X3 are independently selected from H, F, Cl, Br, I, CF3 and CH3, wherein at least one of X1, X2, or X3 is a H, and X4 and X5 are independently selected from H, F, Cl, Br and I; R1 is a linking group; Z1 and Z2 are independently selected from F, Cl, Br, I, CF3, and a perfluoroalkyl group, p is 0 or 1; and M is selected from F, and a cation.

Copolymerization of ethylene, tetrafluoroethylene, and an olefin-containing fluorosulfonyl fluoride: Synthesis of high-proton-conductive membranes for fuel-cell applications

Excellent thermal stability and mechanical properties are exhibited by high-proton-conductive membranes synthesized by a facile copolymerization of tetrafluoro-ethylene, ethylene, and CH2=CHCF2CF 2O-CF2CF2SO2F (see scheme and AFM image). These membranes have been successfully used in a direct MeOH fuel cell.

FLUORINATED IONIC POLYMERS

Described herein are monomers of the formula CH2=CH(CF2)2nOCF2CF2SO2N-(M)SO2Rf where n 1 and M=H or an alkali metal cation, and Rf is C1-4 perfluoroalkyl optionally substituted by one or more ether oxygens, and polymers made therefrom.

IODOFLUOROALKYLSULFONYL FLUORIDES - SYNTHESIS AND CONVERSION TO NEW DERIVATIVES

The thermal reaction of I(CF2)2O(CF2)2SO2F 1 with unsaturated alkenes and alkynes, in the presence of benzoyl peroxide, was studied as a means for preparing reactive iodofluoroalkylsulfonyl fluorides.The following compounds have been prepared and characterized: R(CF2)2O(CF2)2SO2F where R = I(CH2)2, I(CH2)4, CH3CH2, -(CH2)3-, ClCH2CHICH2, ICH=CH (cis and trans), CF3CH=CH (E and Z).The alcohol, HO(CH2)2(CF2)2O(CF2)2SO2F, and olefin, H2C=CH(CF2)2O(CF2)2SO2F, have been also synthesized from the corresponding iodoalkane.Infrared, mass and NMR spectra data are presented in order to support assigned structures.
