Abstract
Polymer or oligomer ionic compound made of a polycationic part (A.sup.+).sub.p comprising a plurality of onium units and a sufficient number of anions X.sup.- to provide electrical neutrality to the compound, characterized in that PA1 the onium units are selected from the group consisting of biaryliodonium, arylsulfonium, arylacylsulfonium, diazonium, organometallic cations comprising a transition metal which is complexed by at least one unsaturated cycle comprising 4 to 12 carbon atoms; PA2 X.sup.- is an imide anion [R.sub.F SO.sub.2 NSO.sub.2 R'.sub.F ].sup.- or a methylide anion [R.sub.F SO.sub.2 C(Q)SO.sub.2 R'.sub.F ].sup.- in which: PA3 1) Q represents: PA4 H--, Cl--, F--, Br--or CN--; PA4 an alkyl radical having 1 to 30 carbon atoms; PA4 an aryl, alkylaryl or arylakyl radical having 6 to 30 carbon atoms; PA4 a group R".sub.F or a group R".sub.F SO.sub.2 ; PA3 2) R.sub.F and R'.sub.F, as well as R".sub.F possibly when X.sup.- is a methylide anion, are independently selected from the group consisting of fluorine, perhaloalkyl groups having 1 to 30 carbon atoms, (perhaloalkyl)alkyloxy groups, perhalogenated cycloaliphatic groups having 3 to 30 carbon atoms possibly containing h…
