    Abstract: Essentially amorphous polyolefines of medium molecular weight are prepared by polymerization of alpha -olefines in the presence of a Ziegler supported catalyst. This catalyst consists of the reaction product of the chloride and/or alcoholates of the tetravalent titanium and of an alcoholate and/or a magnesium compound containing hydroxyl groups and of an aluminiumorganic compound containing chlorine, in which the proportion Al : Cl is 4:1 to 0.8:1. The polymerization is carried out at a temperature of from 100 DEG to 160 DEG C.
