Particles modified, support comprising more olefin polymerization catalyst component comprising more olefin polymerization catalyst obtained by using the same, and process for producing an olefin polymer

摘要

PROBLEM TO BE SOLVED: To provide particles which, when used together with a transition metal compound, give an olefin polymerization catalyst which, when used in a polymerization (e.g. slurry polymerization or gas-phase polymerization) accompanied by the formation of polymer particles, exhibits a high activity, is excellent in shape and particulate properties, and gives a polymer having a narrow mol.wt. distribution; a carrier comprising the same, an olefin polymerization catalyst component comprising the same; an olefin polymerization catalyst prepared by using the same; and a production method for an olefin polymer using the catalyst. ;SOLUTION: There are provided modified particles prepared by contacting (a) particles with (b) a group 7 metal compound and then with (c) a compound having an active-hydrogen- containing functional group or a non-proton-donating Lewis base functional group and an electron-attracting group; a carrier comprising the modified particles; an olefin polymerization catalyst component comprising the modified particles; an olefin polymerization catalyst prepared by using (A) the modified particles, (B) a transition metal compound, and (C) an organometallic compound; and a production method for an olefin polymer using the catalyst.;COPYRIGHT: (C)2001,JPO
