| titleOfInvention | Carried metallocene catalyst and preparation method thereof |
| abstract | The present invention relates to a kind of carried metallocene catalyst, the content of Al is 5%~20% (weight) in the catalyst；Levels of transition metals is 0.01%~0.3% (weight).The catalyst can be used for homopolymerization and the copolymerization of alkene, and obtained polymer morphology is good, does not glue kettle, and catalysis in olefine polymerization activity is not less than 1000 times/hour.The invention further relates to a kind of methods preparing above-mentioned carried metallocene catalyst, the load factor of the alkylaluminoxane and metallocene compound that prepare carried metallocene catalyst with this method is all higher than 70% (weight), it is simple for process, with short production cycle, load metallocene catalyst can be efficiently prepared under mild reaction conditions, the loss of alkylaluminoxane is small in loading process, reduces production cost. |
