Abstract of the Disclosure A catalyst for the polymerization of 1-olefins is pre- pared by reacting a chromate ester fixed on a carrier con- taining silicon dioxide, in the absence of an unsaturated polymerizable hydrocarbon, with an aluminum-organic com- pound and subsequently activating with aluminum-organic compound. No washing liquids that have to be worked up are obtained and the polymers obtained in a high yield have a broad molecular weight distribution and contain a small proportion of high molecular constituents only. The films made therefrom are practically free from specks.
