| titleOfInvention | Process of producing olefin polymer |
| abstract | A process of producing an olefin polymer by polymerizing an olefin in a multi-stage polymerization in the presence of a catalyst composed of a solid catalyst component containing a halogen and titanium, and an organoaluminum compound, while adding, to a reaction vessel for conducting a second-stage or later polymerization or a portion connecting a former part to a latter part, of the multi-stage polymerization reaction vessels,n (a) a polyfunctional electron donor compound in an amount, based on the organoaluminum compound, of 0.001 to 50 in terms of the ratio of the total moles of the functional groups to the mole of aluminum, and (b) a compound different from the compound (a) and selected from a compound having a group of the formula M-O-R (wherein M is an element selected from the group consisting of the group IA, IIA, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIB, VIIA and VIII elements of the periodic table and R is a hydrogen atom or a hydrocarbyl group), oxygen, carbon monoxide and carbon dioxide, in an amount, based on the organoaluminum compound, of 0.001 to 50 in terms of the ratio of the moles of oxygen atom to the mole of aluminum. |
