PROCESSES FOR PRODUCING A FLUOROSULFONYL GROUP-CONTAINING COMPOUND AND A COMPOUND LED FROM THE FLUOROSULFONYL GROUP-CONTAINING COMPOUND

摘要

The invention provides fluorosulfonyl compounds having high polymerizability , a process for the preparation thereof, fluorosulfonyl-bearing polymerizable monomers derived from the compounds, polymers obtained by polymerizing the monomers, and polymers bearing sulfonic acid groups which are derived from t he polymers. Compounds (5) are produced by fluorinating a compound (3) into a compound (4) and decomposing the compound (4). Compounds (7-1) having high polymerizability are produced by subjecting compounds (5-1), which are included among the compounds (5), to thermolysis. Polymers obtained by polymerizing compounds (7-1) are converted into polymers bearing sulfonic ac id groups through alkaline hydrolysis. (3) (4) (5) (5-1) (7-1)
