(57) Abstract: The present invention relates to a method for uniformly dispersing a transition metal metallocene complex on a carrier, comprising: (1) a porous material having a particle size of 1 to 250 microns and an average diameter of 50 to 500 angstroms. (2) slurrying the silica in an aliphatic solvent having a boiling point of less than 110 ° C .; (3) metallocene compound, alumoxane including, providing a solution of a volume of an aromatic solvent, wherein the alumoxane for linear alkyl aluminum Moki San formula is represented by R- (Al (R) -O) x -AlR 2, cyclic alkyl the alumoxane formula: - is represented by (Al (R) -O-) y , in the above formula, x is 1 to 40, y is 3 to 40, and R is a C 1 -C 8 alkyl group And the volume of the solvent is The concentration of alumoxane, smaller than that required to form the slurry, and expressed as Al wt%, is 5-20; (4) contacting the silica slurry (2) with the volume of the solution (3) Causing the pores of the silica to impregnate and dispersing the metallocene compound in the carrier; and (5) evaporating the solvent from the contacted and impregnated silica to recover the dried free-flowing catalyst particles. Related to the method. |
