Abstract (en)

[origin: DE19831804A1] A heterogeneous catalyst system for olefin polymerization comprises: (a) Organometallic compound(s) of Main Group 3 or 4 metal(s); (b) transition metal compound(s) containing Subgroup 3-8 metal(s); and (c) kaolin as the support. An Independent claim is also included for a process for the production of this catalyst system, involving (i) suspending kaolin in an inert solvent and (ii) reacting with compound(s) (a) followed by compound(s) (b) or with a mixture of (a) and (b).
