- 20 - PROCESS FOR POLYMERIZING ETHYLENE ABSTRACT OF THE DISCLOSURE Ethylene or a mixture of ethylene with an .alpha.-olefin having at least 3 carbon atoms is polymerized in the presence of a catalyst formed from (A) a solid catalyst component and (B) an organic aluminum compound of the formula: R5nAlH3-n wherein R5 is C1-6 alkyl and n is 1 or 2. The solid catalyst component is prepared by (1) reacting an aluminum halide with a silicon compound of the formula: R1?Si(OR2)4-? wherein R1 and R2 indepen- dently signify C1-8 alkyl, phenyl or C7-10 aralkyl and ? is 0, 1, 2 or 3, (2) reacting the obtained product with a Grignard compound of the formula: R3MgX1 wherein R3 is C1-8 alkyl, phenyl or C7-10 aralkyl and X1 is halogen, to form a carrier, and then, (3) contacting the carrier with a titanium compound of the formula: (R4O)mTiX24-m wherein R4 is C1-8 alkyl, phenyl or C7-10 aralkyl, X2 is halogen and m is 0, 1, 2 or 3.
