Process for preparing catalyst for olefin polymerization

摘要

Disclosed is a process for preparing a catalyst for polymerizing a mono olefin having 6 through 20 carbon atoms comprising mixing (a) a fatty acid having not less than 3 carbon atoms and (b) aluminum chloride, aluminum bromide or a mixture thereof in an amount of 0.7 through 1.2 mol of the component (b) based upon 1 mol of the component (a), to effect the condensation reaction of both components and a catalyst prepared by said process. This catalyst is suitable for use in the production of an olefin polymer having low viscosity and a high viscosity index.
