摘要：
A process for preparing an ultra-high molecular weight polyethylene by the polymerization of ethylene using a catalyst comprising a solid catalyst component and an organometallic compound, characterized in that said solid catalyst component is a product obtained by contacting the following [A] and [B] together:
[A] the reaction product of a magnesium dihalide and a titanium compound represented by the general formula Ti(OR)₄ wherein R is a hydrocarbon group having 1 to 20 carbon atoms;
[B] the reaction product of an aluminum trihalide and a silicon compound represented by the general formula Si(OR′)₄ wherein R′ is a hydrocarbon group having 1 to 20 carbon atoms.
