| titleOfInvention | PROCESS FOR STARTING POLYMERIZATION OF ETHYLENE OR COPOLYMERIZATION OF ETHYLENE AND ALPHA-OLEFIN IN THE GAS PHASE IN THE PRESENCE OF A CHROMIUM OXIDE CATALYST |
| abstract | THE PRESENT INVENTION CONCERNS A PROCESS FOR STARTING POLYMERIZATION OF ETHYLENE OR COPOLYMERIZATION OF ETHYLENE AND AT LEAST ONE OTHER ALPHA-OLEFINE BY PLACING IN CONTACT, UNDER CONDITIONS OF POLYMERIZATION OR COPOLYMERIZATION IN FLUIDIZED LITTLE AND OUQUIDIZED. ETHYLENE AND POSSIBLY AT LEAST ANOTHER ALPHA-OLEFIN WITH A FILLER POWDER, IN THE PRESENCE OF A CATALYST CONTAINING A CHROME OXIDE COMPOUND ASSOCIATED WITH A GRANULAR SUPPORT AND ACTIVATED BY THERMAL TREATMENT, THIS CATALYST BEING USED IN WORK IN THE FORM OF A PREPOLYMER, PROCESS CHARACTERIZED IN THAT THE FILLER POWDER USED IS PREVIOUSLY SUBJECT TO A TREATMENT BY PLACING THE SAID FILLER IN CONTACT WITH AN ORGANOALUMINIC COMPOUND, SUCH AS THE POLYMERIZATION IN IMMEDIATE OR DEMONSTRATION OF COPARYREATION CONTACT WITH ETHYLENE AND POSSIBLY AT LEAST ONE OTHER ALPHA-OLEFIN WITH THE PREPOLYMER POWDER IN THE PRESENCE OF THE PREPOLYMER. |
