Abstract: CATALYST SYSTEM FOR THE POLYMERIZATION OF OLEFINS CONSISTING OF (1) A POWDERED INORGANIC CARRIER AND, APPLIED THERETO, (2) A ZEIGLER-TYPE CATALYST CONSISTING OF (2,1) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF CHLORIDES, OXYCHLORIDES AND ALKOXYCHLORIDES OF TITANIUM, ZIRCONIUM AND VANADIUM AND (2.2) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF SATURATED METAL ALKYLS, SATURATED METAL ALKOXYALKLS AND SATURATED METAL ALKYL HALIDES OF THE METALS ALUMINUM, MAGESIUM AND ZIND. THE CHARACTERIZING FEATURE OF THE CATALYST SYSTEM OF THE INVENTION IS THAT THE CARRIER (1) HAS BEEN OBTAINED BY HEATING A SUBSTANCE OF THE FORMULA

,H MG(SN(OH)6)

THIS CATALYST SYSTEM IS VERY EFFLICIENT AND ENABLES THE MOLECULAR WEIGHT OF THE POLYMERS TO BE WELL REGUALTED BY MEANS OF HYDROGEN.
