摘要: For the (co) polymerization of ethylene with other 1-olefins, a Ziegler catalyst which comprises the product from the reaction of a magnesium alkoxide suspended or dispersed as ge in an inert solvent with a tetravalent transition metal compound and is subjected to a thermal after-treatment for a period of not more than 180 minutes is prepared. The catalyst gives a high yield of a polymer powder which has a broad molar mass distribution and is best suited to the production of films, hollow bodies and pipes.
