发明名称 PROCESS OF PREPARATION OF CATALYTIC SUPPORT AND SUPPORTED METALLOCENE CATALYSTS FOR PRODUCTION OF HOMOPOLYMERS AND COPOLYMERS OF ETHYLENE WITH ALFA - OLEFINS, OF HIGH AND ULTRA HIGH MOLECULAR WEIGHT AND WITH BROAD MOLECULAR WEIGHT DISTRIBUTION IN SLURRY, BULK AND GAS PHASE PROCESSES AND PRODUCTS THEREOF
摘要 The present invention relates a process for the preparation of catalytic support and the supported metallocene catalysts used in the production of ethylene homopolymers and ethylene copolymers with α-olefins, of high and ultra high molecular weight with broad molecular weight distribution, in gas or liquid phase polymerization processes, the latter being in slurry, bulk or suspension, and the products obtained from these processes.
