| 摘要 |
<p>The present invention relates to a Ziegler-Natta catalyst comprising a solid, ligand-modified catalyst component formed at least from
(a) a compound of Group 1 to 3 of the Periodic Table (IUPAC),
(b) a transition metal compound of Group 4 to 10 of the Periodic Table (IUPAC), or a compound of an actinide or lanthanide,
(c) one or more organic ligand compound(s) which is/are selected from organic compounds comprising a cyclopentadienyl anion backbone, and
(d) a compound of Group 13 of the Periodic Table,
wherein the catalyst component of said Ziegler-Natta catalyst is formed in an emulsion/solidification method, to a process for the production of such a catalyst, and to a process for the production of an olefin (co-)polymer in the presence of such a catalyst.</p> |
