摘要

An ionic compound comprising at least one group A+X-, comprising: a cationic group A+ selected from the group consisting of biaryliodonium, arylsulfonium, arylacylsulfonium, diazonium and organometallic cations comprising a transition metal complexed with at least one unsaturated cyclic compound comprising 4-12 carbon atoms, said cationic group being part of a polymer chain; wherein X- is an imide anion, [FSO2NSO2R'F]- or [RFCH2OSO2NSO2R'F]- or [(RF)2CHOSO2NSO2R'F]-, or a methylide anion [FSO2C(Q)SO2R'F]-, or a [RFCH2OSO2C(Q)SO2R'F]- or [(RF)2CHOSO2C(Q)SO2R'F]31 .
