More Information
Summary:The present invention relates to a supported cobalt catalyst consisting of (a) cobalt compounds, (b) organoaluminium compounds, (c) water or OH-acidic compounds, (d) inorganic or polymeric organic support materials and (e) modifiers selected from the group comprising tertiary phosphines, to the production thereof and to the use thereof for the polymerization of unsaturated compounds, in particular of conjugated dienes, in the gas phase. With the assistance of the catalysts according to the invention, it is possible to achieve gas phase polymerization of conjugated dienes with an elevated content of lateral double bonds in the polymers.
