Abstract: PROBLEM TO BE SOLVED: To provide a preparation process for a catalyst which shows a high activity with respect to the polymerization of ethylene and an α-olefin of a higher molecular weight and synthesizes an ethylene polymer and a copolymer having a comparatively narrow molecular weight distribution and a uniform branch distribution.
SOLUTION: The preparation process for the catalyst comprises supplying porous silica having a specific pore volume and an almoxane solution, of which the volume is less than the pore volume of silica, in an amount sufficient to supply a predetermind amount of aluminum to bring both of them into contact with each other and impregnating the pores of silica with the solution. Before the contact, an organomagnesium compound is added to the silica to be reacted with a reactive hydroxy group and a non-metallocene transition metal compound is added to the reaction mixture. After the contact, dried silica particles impregnated with solid almoxane are collected.
