Verfahren zur Herstellung eines Pyrolyseproduktes aus Polyacrylnitril und dessen Copolymeren, mit dem Verfahren erhaeltliche Pyrolyseprodukte und deren Verwendung

The invention relates to pyrolysis products made of polyacrylnitrile or polyacrylnitrile copolymers. These are obtained by dissolving the polymer or copolymer in a suitable solvent and then applying the polymer solution in the form of a think coating on a substrate and then tempering the coated substrate in the range of 100<degrees>C until below the temperature of decomposition of the substrate.
