Abstract:
The present invention relates to a process for preparing a solid catalyst component suitable for producing polyethylene and its copolymers, said process comprising the steps of: (a) contacting a dehydrated support having hydroxyl groups with a magnesium compound having the general formula MgR 1 R 2 ; (b) contacting the product obtained in step (a) with modifying compounds (A) and/or (B) and/or (C), wherein: (A) is at least one oxygen and/or nitrogen comprising organic compound; (B) is a compound having the general formula R 11 f (R 12 O) g SiX h , (C) is a compound having the general formula (R 13 O) 4 M, and (c) contacting the product obtained in step (b) with a titanium halide compound having the general formula TiX 4 , wherein Ti is a titanium atom and X is a halide atom, wherein an organometallic compound is added after step (a) and before step (b). The invention also relates to a solid catalyst component obtainable by said process. The invention further relates to a process for producing polyethylene and its copolymers in the presence of the solid catalyst component and a cocatalyst.

Claim (Index 16):
The process according to  claim 2  wherein\n the molar ratio of compound (A) to Mg is from 0.01 to 10 and/or the molar ratio of compound (B) to Mg is from 0.01 to 5 and/or the molar ratio of compound (C) to Mg is from 0.01 to 5; \n the organometallic compound is used in a molar ratio of the organometallic compound to titanium halide compound of between 0.1 and 1.5; \n the molar ratio of titanium halide compound to Mg is from 0.01 to 10.
