Title:
OLEFIN POLYMERIZATION CATALYST AND PREPARATION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/151504
Kind Code:
A1
Abstract:
An olefin polymerization catalyst and preparation method and use thereof are
provided. The catalyst component comprises (I) an active magnesium halide,
(2) a titanium compound containing at least one Ti-halide bond supported thereon,
and (3) an electron donor selected from one or more sulfonyl-containing compounds
having the following formula. There are two methods for preparing such solid
catalyst component: I) treating the active magnesium halide (1) particles with
alkylaluminum, subsequently adding the electron donor (3), treating it with
the solution of titanium compound (2) one or more times; II) adding spherical
magnesium chloride alcoholate particles to the solution of titanium compound
(2), subsequently adding the electron donor (3), treating it with the solution
of titanium compound (2) one or more times. The catalyst system comprises such
solid catalyst component, a cocatalsyt (alkylaluminum compound) and an external
electron donor.
