SUPPORTED CATALYST FOR 1-OLEFIN (S) (CO) POLYMERIZATION |
| abstract |
The present invention relates to a supported catalyst composition useful for the polymerization of olefins and a process for preparing the same. A catalyst is prepared by first reacting a trialkaluminum compound with a transition metal metallocene and then reacting the resulting material with an undehydrated support material to produce a solid product containing at least 20q of support material per millimolar of the transition metal. The resulting supported catalyst has an activity comparable to that of the supported catalyst prepared by the prior art, which is at least 20%, preferably 50% less active than the content used in existing known metallocene-alumoxane catalysts. It is obtained based on the metal content. The present invention particularly relates to the use of undehydrated silica gel with 6-20% by weight of water as catalyst support material. |
