摘要： CATALYTIC FOR THE LOW PRESSURE POLYMERIZATION AND COPOLYMERIZATION OF OLEFINS ARE PROVIDED WHICH COMPRISES AN ACTIVATOR WHICH IS AN ORGANOMETALLIC COMPOUND AND A SOLID PRODUCT OBTAINED BY REACTING A SUPPORT COMPRISED OF A SOLID BIVALENT METAL COMPOUND WITH AN ORGANOMETALLIC COMPOUND, SEPARATING THE RESULTING SOLID PRODUCT, AND THEN REACTING THIS PRODUCT WITH A HALOGENATED DERIVATE OF A TRANSITION METAL. THE ORGANOMETALLIC COMPOUND REACTED WITH THE SUPPORT MAY BE THE SAME OR DIFFERENT FROM THE ACTIVATING COMPOUND. THE POLYMERIZATION AND COPOLYMERIZATION OF OLEFINS IS CARRIED OUT USING THESE CATALYST.

摘要： THE CATALYST FOR THE POLYMERIZATION AND COPOLYMERIZATION OF OLEFINS IS COMPOSED OF (A) AT LEAST ONE ORGANOMETALLIC COMPOUND AND (B) A SOLID CATALYTIC COMPONENT OBTAINED BY REACTING A SUPPORT COMPRISED OF SILICA, ALUMINA OR BOTH SILICA AND ALUMINA WITH A COMPOUND OF THE FORMULA MRNXM-N IN WHICH M IS ALUMINUM OR MAGNESIUM, R IS A HYDROCARBON RADICAL, X IS HYDROGEN OR HALOGEN, M IS THE VALENCE OF M AND N IS A WHOLE NUMBER OF NOT LESS THAN 1 NOR GREATER THAN M, SEPARATING THE SOLID PRODUCT OF THE REACTION, REACTING THIS PRODUCT WITH AN EXCESS OF A HALOGEN-CONTANING TRANSITION METAL COMPOUND AND SEPARATING THE SOLID REACTION PRODUCT. THE POLYMERIZATION OF A-OLEFINS AND COPOLYMERIZATION OF A-OLEFINS WITH ONE ANOTHER AND WITH DIOLEFINS BY MEANS OF THE PRESENT CATALYSTS ARE CARRIED OUT WITH A HIGH RATE OF PRODUCTIVITY.
