ABSTRACT:
A Ziegler catalyst in which the transition metal component has been prepared by reacting a transition metal compound of titanium, zirconium, vanadium or chromium with a gel-like dispersion of a magnesium alcoholate is used for the preparation of poly-1-olefins, in particular polyethylene. The co-catalyst used is an organoaluminum compound. The polymers are obtained in a high to very high yield, and it is possible to control the particle size distribution of the polymers.
