| Abstract: | The loading process of silica gel-supported metallocene catalyst of （1-Me-3-nBuCp）2ZrCl2/methylaluminoxane（MAO） was studied. The effects of activation temperature of silica gel,loading temperature,stirring mode,amount of MAO used to pretreated silica gel on polymerization activity of the catalyst were discussed. The results showed that under the conditions of activation temperature 600℃,loading temperature-30℃,the mole rate of aluminium to silica 3,the mole ratio of aluminium to zircomium 50,the activity of catalyst was 5454g/g and the bulk density of product was 0.36g/cm3. |
| Keywords: | metallocene catalyst loading silica gel activity |
