Title:

SOLID TITANIUM CATALYST COMPONENT AND UTILIZATION THEREOF IN OLEFIN POLYMERIZATION CATALYST

Document Type and Number:

WIPO Patent Application WO/1997/013794

Kind Code:

A1

Abstract:

A process for preparing a solid titanium catalyst component, comprising the steps of: (1) preparing a suspension containing a solid material comprising a polycarboxylic ester borne on a solid product prepared by bringing a magnesium compound and a first titanium compound into contact with each other; (2) separating the solid material from the suspension; and (3) bringing the solid material and a second titanium compound into contact with each other under heating, characterized in that the solid material is held at a temperature in the range of from 70 to 130 �C during the period between the separation of the solid material from the suspension in the step (2) and the transfer of the separated solid material to the step (3).
