    • Catalysts for use in the polymerization of 1-olefins (in combination with aluminium organometallic compound cocatalysts) are made by:

      A) removing surface absorbed water from a support material which is silica and/or alumina having surface hydroxyl groups by

      (i) drying or calcining the support at an elevated temperature, or
      (ii) reacting the support with an organosilicon compound, and

      B) reacting the treated support with

      (i) an organosilicon compound which is reactive with the surface hydroxyl groups and which has the formula (R 3 Si) 2 NH, in which the R groups, which may be the same or different, are C 1 -C 20 alkyl, aryl, akaryl or aralkyl groups, the amount of the organosilicon compound being in excess of that required to react with the surface hydroxyl groups present in the support,
      (ii) a Group IIA organometallic compound or a complex of a Group IIA organometallic compound with a Group IIIA organometallic compound, and
      (iii) at least one compound of a Group IVB or Group VB transition metal.
