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.
