Abstract
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 XAl(OY), 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 TiXwherein 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), silicon halide represented by formula SiXand alkoxy silane represented by formula Si(OR), wherein Rand Rare an aromatic or aliphatic alkyl group and wherein X is halide. Alkyl metal (C) is synthesized by reacting alkyl aluminum compounds represented by formula AlRwith a secondary amine having formula HNRand then by reacting with alkyl magnesium compounds represented by formula RMgR, wherein R, R, Re and Rare 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.
