PURPOSE:To obtain an excellent support for a solid transition metal catalyst, by copulverizing a liquid halohydrocarbon with a magnesium halide and a liquid oxygen-containing organic compound in such a manner that at least part of said liquid halohydrocarbon is added just prior to completion of copulverization. CONSTITUTION:In the production of a support for a solid transition metal catalyst by copulverizing a magnesium halide with a liquid halohydrocarbon and a liquid oxygen-containing organic compound, at least part of said liquid halohydrocarbon is added just prior to completion of copulverization. In order to obtain a good catalyst support, it is desirable that the ratio of the liquid oxygen- containing organic compound to the magnesium halide is 0.1-0.2ml/g or below, and the ratio of the liquid halohydrocarbon to the magnesium halide is 0.1ml/g or above. As the magnesium halide used, magnesium chloride is particularly preferable, though it may be replaced with magnesium chloride containing about 0.1mol of water per mol of it. |
