ABSTRACT:
Hard abrasion-resistant carbon is obtained from polymerized halohydrocarbons by elimination of hydrogen halide in a two-stage process carried out so that in the first decomposition stage, which is carried out at temperatures within the range from 140.degree. to 250.degree.C, a definite amount (not less than 5% by weight and not more than 50% by weight) of the total amount of hydrogen halide capable of being split off is removed. Appropriately shaped end products can be obtained by using raw materials having a globular, cylindrical or other shape. The carbon obtained is suitable as the stationary phase for chromatographic separation and analysis of mixtures.
