Abstract: NEW CATALYSTS FOR THE POLYMERIZATION OF OLEFINS, MORE PARTICULARLY FOR THE POLYMERIZATION OF ETHYLENE AND MIXTURES THEREOF WITH HIGHER ALPHA-OLEFINS ARE DISCLOSED, AS WELL AS METHODS FOR PREPARING THE SAME, AND FOR POLYMERIZING OLEFINS THEREWITH. THE NEW CATALYSTS ARE PREPARED BY MIXING A HYDRIDE OR ORGANOMETALLIC COMPOUND OF A METAL BELONGING TO GROUP I, II OR III OF THE MENDELYEEV PERIODIC TABLE WITH THE PRODUCT OBTAINED BY CONTACTING A TITANIUM COMPOUND WITH THE SOLID REACTION PRODUCT OF A HYDRATED MAGNESIUM HALIDE AND AN ORGANOMETALLIC COMPOUND OF ONE OF SAID GROUPS I TO III METALS, IN A MOLAR RATIO ORGANOMETALLIC COMPOUND/H2O OF AT LEAST 1.
