Abstract
The invention relates to a new bis(trialkylsilyl) chromate of the formula ##STR1## where n is approximately 1-2. Such a compound can be prepared by causing a corresponding silyl halide to react with silver chromate. The product is especially suitable for the polymerization and copolymerization of ethylene, the formed polymer having a high molar mass and a wide molar mass distribution.
