OLEFIN POLYMERIZATION CATALYST MADE FROM A TRIALKYL ALUMINUM MIXTURE, SILICA ACID AND METALLOCEN. |
abstract |
A highly active, alumoxane-metallocene-supported catalyst for the polymerization of 1-olefins is prepared by reacting an undehydrated silica gel with a mixture of trimethyl aluminum and triisobutyl aluminum to obtain a silica-alumoxane product which then reacting with a metallocene of group IVB and / or group VB so as to obtain an active catalyst in powder form suitable for use in gas or mud phase reactors, by removal of solvents and by drying. |
