A HIGH SURFACE AREA SILICON DERIVATIVE FREE MAGNESIUM- TITANIUM CATALYST SYSTEM FOR ETHYLENE POLYMERIZATION AND PROCESS OF PREPARATION THEREOF |
摘要 |
The present invention relates to a high surface area silicon derivative free magnesium-titanium catalyst system for ethylene polymerization comprising: magnesium mixed alkoxide and titanium chloride. The present invention also provides a simple process for the preparation of high surface area silicon derivative free magnesium-titanium catalyst system for ethylene polymerization by reacting magnesium alkoxide precursor with titanium compound using dialkyl dialkoxy silane as external donor. The invention further relates to the process for ethylene polymerization using the silicon derivative free magnesium-titanium catalyst system and polyethylene produced by the catalyst system having narrow molecular weight distribution and higher bulk density. |
