Abstract: Polyolefins having a broad molecular weight distribution are obtained in a very high yield even using a catalyst based on a reaction product of a magnesium alcoholate with titanium tetrachloride, if the hydrocarbon-insoluble product of the reaction of the magnesium alcoholate with titanium tetrachloride is heated to a fairly high temperature with a chloroalkoxytitanate, in order to split off alkyl chlorides.

Abstract: Copolymers of ethylene and higher 1-olefins which are suitable for the manufacture of thin films, are preferably prepared in a two-step process, the first step yielding a polymer having a high molecular weight, the second step giving a polymer having a low molecular weight. The films obtained from these copolymers have improved mechanical properties as compared to films manufactured from known corresponding raw materials. The mechanical properties are furthermore uniform in longitudinal and in transverse direction.
