A filled polyolefin molding material having a very high filler content and containing no filler-free polymer and no polymer-free filler is obtained when the Ziegler catalyst is initially formed on the filler and the catalyst-charged filler is then used for the polymerization without addition of further catalyst or activator. The molding material is highly suitable, in particular when it has a high content of aluminum powder, for the production of molded parts having good thermal conductivity and a high electrical volume resistance. |
