TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The zerovalent transition metal is palladium or nickel (preferably bis(1,5-cyclooctadiene)nickel(0)). The neutral ligand is 2,2'-bipyridine. The zerovalent transition metal and neutral ligand are in the form of a complex.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The polymerization is performed in a solvent (preferably N,N-dimethylformamide, toluene, tetrahydrofuran, acetone, anisole, acetonitrile, N,N-dimethylacetamide or N-methylpyrrolidinone). In the process, an accelerator is present, and a copolymer is formed by polymerizing (I) and a compound of formula Ar'-S(O)2-N(M)-(S(O)2-Rf-S(O)2-N(M))m-S(O)2-Ar'. The polymer is a homopolymer or copolymer.Ar'=univalent group of formula (iv)-(vi);andT1=boronic acid or its salt, boronic ester or borane. Preferred Definitions:    M=K, Na, Li or H;    Rf=linear 2-4C perfluorinated alkylene;    m=1;    Q=SO2;    X=Br;and    Ar=dibenzofuran-3-yl (substituted at 3-position by X) or biphenyl-4-yl (substituted at 4' position by X).    EXAMPLE - A flask (A1) was charged with N,N'-bis(7-bromo-dibenzothiophene-5,5-dioxide-3-sulfonyl)-octafluorobutane-1,4-disulfonamide, disodium salt (5.593 g), 3,7-dibromo-dibenzothiophene-5,5-dioxide (1.122 g) and dimethylformamide (DMF) (40 ml). A flask (B1) was charged with bis(1,5-cyclooctadiene)nickel(0) (4.45 g), 1,5-cyclooctadiene (1.75 g), 2,2'-bipyridine (2.52 g), and DMF (20 ml). The flasks (A1) and (B1) were heated to 70 degrees C under nitrogen and stirred to dissolve the solids. The catalyst solution was added dropwise to the monomer solution by cannula. The dark solution was stirred at 70 degrees C to give a hard gel then kept at temperature overnight. The reaction mass was heated to 100 degrees C for 1 hour without any change in texture then cooled to room temperature. The gel was transferred to a blender containing concentrated hydrochloric acid to precipitate the solid polymer and disperse into particles. The polymer was collected by vacuum filtration and washed with hexane and concentrated hydrochloric acid. After drying in a vacuum oven at 70 degrees C, the polymer weighed 5.52 g. The polymer was dissolved in dimethylsulfoxide (DMSO) (200 ml), filtered, washed with DMSO (50 ml), and re-precipitated in concentrated hydrochloric acid. The polymer was dried in the vacuum oven at 85 degrees C under nitrogen purge to give poly(oligo(3,7-dibenzothiophene-5,5-dioxide)-sulfonimide-1,4-octafluorobutane-sulfonimide) of formula (II).
