<p>Olefin polymer is prepd. using a catalyst consisting of a combination of an organoaluminium compound and a solid catalyst obtained by reacting organic oxides and/or halogenated compounds of (A) Ti, (B) V, (C) Zr or Hf, and/or an organoaluminium compound, e.g. of the formula AlRnXo-n (where R = 1-20C hydrocarbon group, X = halogen atom, and n = 0-3) or Alr1mBr3-m (where R1 = 1-20 hydrocarbon gp. and m = 0-3). Manufacture of blow moulding polyolefin, especially polyethylene.</p> |
