Abstract: There are disclosed new catalysts for the polymerization of olefins and which comprise the products of reaction between organometallic compounds or hydrides of metals of Groups I, II or III of the Mendelyeev Periodic Table and the product obtained by reacting a liquid halogenated compound of titanium or vanadium with a solid carrier containing chemically uncombined water and having the formula Mg O. (Mg(OH)2)x. (H2O)y, WHEREIN X IS A NUMBER GREATER THAN O and may be 100 or higher; y is a number between 0 and 1; (Mg(OH)2)x expresses the number of hydroxyls present in the carrier, however combined; and (H2O)y represents the number of chemically uncombined molecules of water present in the carrier. The catalysts are very active and use thereof in the polymerization of olefins results in high yields of polymers having a low content of foreign substances.

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.
