Abstract:
1. Silicone rubber compounds containing 0.5% to 60% by weight of the fumed silanized silica having the following characteristic physicochemical data: and 40% to 99.5% by weight, based on the total mass, of an organopoly-siloxane of the formula where R=alkenyl, alkoxy, aryl, oxime, acetoxy, alkyl radicals, having 1 to 50 carbon atoms, unsubstituted or substituted by O, S, F, Cl, Br, I, in each case identical or different, and/or polystyrene, polyvinyl acetate, polyacrylate, polymethacrylate and polyacrylonitrile radicals having 40-10 000 repeater units, Z=OH, Cl, Br, acetoxy, amino, amineoxy, oxime, alkoxyamido, alkenyloxy, acryloxy or phosphate radicals, where the organic radicals contain up to 20 carbon atoms, and in each case identical or different, where Z′=oxime, alkoxy, acetoxy, amino, amido, n=1-3, and
