Claims (12)

1. A method of preparing a supported catalyst system comprising (a) bringing the porous support into contact with a solution comprising a metallocene catalyst component and an activator, wherein the total solution volume is in the range of a volume less than three times the total pore volume of the porous carrier up to a volume exceeding a single total pore volume of the porous support; and (b) drying the resulting catalyst system.  2. A method of preparing a supported catalyst system, comprising (a) bringing the porous support into contact with a solution comprising a metallocene catalyst component and an activator, wherein the total volume of the solution is in the range from a volume less than the volume at which the suspension forms to the volume exceeding a single total pore volume of the porous support; and (b) drying the resulting catalyst system.  3. A method of preparing a supported catalyst system comprising contacting a porous support with two or more solutions, one of which includes a metallocene catalyst component, and the other includes an activator, where the joint volume of the solutions is in the range of values from a volume less than that in which a suspension is formed, to a volume exceeding a single total pore volume of the porous support.  4. The method according to p. 1 or 2, where the total volume of the solution (s) is in the range of values from a volume less than the volume at which a suspension is formed to a volume exceeding a single total pore volume of the porous support.  5. The method according to any one of the preceding paragraphs, where the total volume of the solution (s) is from 2.5 times the total pore volume of the porous carrier to 1.05 times the total pore volume of the porous carrier.  6. The method according to any one of the preceding paragraphs, where the total volume of the solution (s) is from 2.4 times the total pore volume of the porous carrier to 1.4 times the total pore volume of the porous carrier.  7. The method according to any one of the preceding paragraphs, where the solution (s) comprises (s) two or more metallocene catalyst components and / or two or more activators.  8. The method according to any one of the preceding paragraphs, where the porous carrier is dehydrated before being brought into contact with the solution (s).  9. The method according to any one of the preceding paragraphs, where the molar ratio between the activator metal and the transition metal of the metallocene catalyst component is from 20: 1 to 800: 1.  10. A method for polymerizing olefins individually or in combination with one or more other olefin monomers, comprising polymerizing in the presence of a supported catalyst system prepared by the method of any one of the preceding paragraphs.  11. The supported catalyst system obtained by the method according to any one of claims. 1-9.  12. The method according to p. 1, where the solution includes dimethylsilyl (tetramethylcyclopentadienyl) (adamantylamido) titanedichloride.
