    • A process for synthesizing a catalyst component for manufacturing ethylene polymer and co-polymer. The present invention provides a process for synthesizing catalyst component (A), comprising forming a complex by contacting the solid intermediate (B) with an aluminum compound represented by formula X 3-n Al(OY) n , and alkyl metal (C), wherein X is halide, Y is a hydrocarbon group or chelating carbonyl group, and wherein 1 is less than or equal to n which is less than or equal to 3, and then contacting the complex with titanium halide having formula ΗX4 wherein X is halide. Solid intermediate (B) is formed by reacting magnesium metal with alkyl halide in the presence of alkoxy aluminum represented by formula Al(OR a ) 3 , silicon halide represented by formula SiX 4 and alkoxy silane represented by formula Si(OR b ) 4 , wherein R a and R b are an aromatic or aliphatic alkyl group and wherein X is halide. Alkyl metal (C) is synthesized by reacting alkyl aluminum compounds represented by formula A1R C 3 with a secondary amine having formula HNRd2 and then by reacting with alkyl magnesium compounds represented by formula R6MgR^ wherein R c , R d , Re and R f are an aromatic or aliphatic alkyl group. The catalyst component is suitable for producing ethylene polymer and co-polymer with narrow molecular weight distribution as well as improved branching compositional distribution.
