ABSTRACT:
The invention relates to a method for preparing polymers of ethylene and propylene, or of copolymers of ethylene and alpha olefins such as propylene 1-butene and 1-hexene or alpha omega dienes such as alpha omega octadiene, respectively, by polymerization within a temperature range from -80.degree. to 150.degree. C. in the presence of a halogen free Ziegler type catalyst system consisting of a cyclopentadienyl compound containing a transition metal and of an aluminum alkyl compound, whereby the polymerization is made in the presence of catalyst system consisting of the following components:
