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: HOE 77/F 207 PROCESS FOR IMPROVING THE PROCESSING PROPERTIES OF POWDERY POLYOLEFINS of the disclosure: The invention relates to a process for improving the processing properties of powdery polyolefins. It is endeavored by this process to obtain a polyolefin powder which can be processed on screw extruders to an almost bubble-free product. The polyolefin powder is heated to a temperature of between 40.degree. C and its melting point and introduced into a gap between two gap forming elements. In this gap, the powder is compressed with a pressure of from 0.1 to 10 t per cm of gap length, and the powder so compressed is then comminuted.

Abstract: of the disclosure: A process for preparing a catalyst for the polymerization of 1-olefins and a process for preparing polyolefins using said catalyst. The catalyst is prepared by reacting a carrier comprising a silicon dioxide, an aluminum oxide, or mixture thereof, having a content of hydroxyl groups with a magnesium compound of the formula RMgX wherein R is a hydrocarbon radical having 1 to 20 carbon atoms and X is chlorine, bromine or iodine, the reaction product is reacted with a halogencontaining titanium compound, and the resultant product is subsequently reacted with an organo-metallic compound.
