Modifizierte Teilchen, Katalysator für die Olefinpolymerisierung unter deren Verwendung und Verfahren zur Herstellung von Olefinpolymer

摘要

Modified particles (A) obtainable by contacting particles (a) with a metal compound (b) selected from compounds of the Group VI, VII and XIV metal elements and compounds of the lanthanide series, and then contacting the particles with a compound (c) having a functional group containing active hydrogen or a non-proton donative Lewis basic functional group, and an electron-withdrawing group; a carrier composed of the modified particles; a catalyst component for olefin polymerization composed of the modified particles; a catalyst for olefin polymerization obtainable by contacting the modified particles (A) and a transition metal compound (B), or further an organometallic compound (C); and a process for producing an olefin polymer with the catalyst.
