Title:
PRODUCTION METHOD FOR FLUORINE-CONTAINING SULFONIMIDE POLYMER
Document Type and Number:
Japanese Patent JP2002212234
Kind Code:
A
Abstract:
To provide a production method wherein a high-purity fluorine- containing sulfonimide polymer can easily be obtained in a high yield with a simple synthetic reaction.
A CF2=CFRf1SO2NXSO2Rf2/CF2=CF2 polymer is produced by reacting a CF2=CFRf1SO2F/CF2=CF2 copolymer with a compound represented by Ff2SO2NH2 or (Rf2SO2NSiR1R2R3)-E+. In those formulas, X is an alkali metal atom; Rf1 and Rf2 are each a perfluoroalkylene; R1, R2, and R3 are each an alkyl; and E+ is a monovalent cation.
