Titanium catalyst component for olefin polymerization and process for polymerization of olefin using the catalyst component |
摘要 |
Disclosed is a titanium catalyst component for ethylene polymerization obtained by contacting [A] a solid magnesium aluminum complex containing magnesium, halogen, aluminum and an alkoxy group and/or alcohol having at least 6 carbon atoms, with [B] a tetravalent titanium compound. The solid magnesium aluminum complex [A] is obtained by contacting (a-1) a magnesium solution formed from a halogen-containing magnesium compound, an alcohol having at least 6 carbon atoms and a hydrocarbon solvent, with (a-2) an organoaluminum compound. Also disclosed is a process for ethylene polymerization comprising polymerizing ethylene or copolymerizing ethylene with an alpha -olefin having 3 to 20 carbon atoms in the presence of a catalyst for ethylene polymerization comprising [I] the above-mentioned titanium catalyst component for ethylene polymerization and [II] an organoaluminum compound catalyst component. |
