A catalyst system suitable for the polymerization of C.sub.2 -C.sub.10 -alk-1-enes comprising, as active ingredients, a complex compound of metals in Sub-groups IV and V of the Periodic Table and an oligomeric alumoxan compound is obtained by a procedure in which metals in Sub-groups IV and V of the Periodic Table are mixed with the oligomeric alumoxan compound and the resulting mixture is then applied to finely divided polymer. The catalyst system of the invention can be isolated after manufacture and is particularly suitable for the gas-phase polymerization of C.sub.2 -C.sub.10 -alk-1-enes.

Isolatable catalyst system suitable for the polymerization of C.sub.2

Propylene polymers have a molecular weight ratio Q (M.sub.w /M.sub.n) of from 6 to 30 and are obtainable by Ziegler-Natta polymerization in the presence of hydrogen as molecular weight regulator and are particularly suitable for the production of films and moldings.
