ABSTRACT:
When reacting the reaction product of silicon dioxide and/or a metal oxide and a Grignard compound with a soluble titanium compound, there is obtained a catalyst for the polymerization of 1-olefins, which gives a very high yield and allows a good control of the molecular weight by means of hydrogen without making necessary a separation of the excess of metallo-organic compounds and/or the excess of titanium compounds from the catalyst carrier.
