摘要： 1. PROCESS FOR THE PREPARATION OF CATALYST FOR THE POLYMERIZATION OF ETHYLENE AND FOR THE COPOLYMERIZATION OF ETHYLENE AND AN ALPHA-OLEFIN, SAID CATALYST CONSISTING ESSENTIALLY OF AN ORGANOMETALLIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF AN ALUMINUM TRIALKYL A ZINC DIALKYL AND A DIALKYL HALIDE OF ALUMINUM WHEREIN EACH ALKYL GROUP CONTAINS 1 TO 4 CARBON ATOMS, AND THE PRODUCT OF INTER-REACTION OF A HALOGENATED DERIVATIVE OF A TRANSITION METAL SELECTED FROM THE GROUP CONSISTING OF CHLORIDES, BROMIDES AND OXYHALIDES OF METALS OF GROUPS IVB AND VB OF THE PERIODIC SYSTEM, IN THE LIQUID STATE AND A SOLID GRANULAR SUPPORT CHARACTERIZED BY IMPREGNATING AT A TEMPERAURE BETWEEN 50 AND 160*C., FOR A TIME NOT LESS THAN 30MINUTES WITH THE LIQUID HALOGENATED DERIVATIVE OF THE TRANSITION METAL THE GRANULAR SUPPORT TO FORM A SUPPORT WHEREIN SAID HALOGENATED COMPOUND FORMS 5 TO 25 PERCENT BY WEIGHT OF THE SUPPORT OBTAINED BY SUBJECTING TO AN ACTIVATION TREATMENT A MAGNESIUM SALT OF AN ORGANIC ACID SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM OXALATE, FORMATE, LACTATE, TARTRATE, ACETATE, BENZOATE AND CITRATE CONTAINING UP TO 5 MOLECULES OF WATER OF CRYSTALLIZATION, OR A DOUBLE ALKALI METAL AND MAGNESIUM SALT OF SAID ORGANIC ACID CONTAINING UP TO 8 MOLECULES OF WATER OF CRYSTALLIZATION, THE ACTIVATION TREATMENT CONSISTING ESSENTIALLY OF HEATING THE MAGNESIUM SALT OR THE DOUBLE ALKALI METAL AND MAGNESIUM SALT IN A CURRENT OF INERT GAS WHICH IS ANHYDROUS OR HAS A HUMIDITY NOT GREATER THAN 10 PERCENT BY WEIGHT OF SATURATION, HEATING TAKING PLACE GRADUALLY TO A TEMPERATURE AT LEAST 20-30* C., BELOW THE DECOMPOSITION POINT OF THE SALT AND MAINTAINING THE SALT AT TIS TEMPERATURE FOR 5 TO 50 HOURS, SAID INTER-REACTION PRODUCT OF THE HALOGENATED DERIVATIVE OF THE TRANSITION METAL AND THE SOLID SUPPORT BEING CONTACTED WITH THE ORGANOMETALLIC COMPOUND IN A RELATIVE AMOUNT SUCH THAT THE MOLAR RATIO OF THE ORGANOMETALLIC COMPOUND TO THE TRANSITION METAL FIXED ON THE SUPPORT IS 20 TO 150.

摘要： Novel catalyst compositions comprising three or more transition metals are effective in increasing catalyst efficiency, reducing polydispersity, and increasing uniformity in molecular weight distribution when used in olefin, and particularly, linear low density polyethylene (LLDPE), polymerizations. The resulting polymers may be used to form differentiated products including, for example, films that may exhibit improved optical and mechanical properties.
