Titanium-aluminium catalysts with alkoxy ligands supported on aluminium oxide for ethylene polymerization

Activity of a model titanium-aluminium catalyst system with n-BuO-ligands has been investigated in the polymerization of ethylene. The effect of the concentration of titanium compound on the support, the Al/Ti molar ratio, and catalyst concentration in the polymerization process on polyethylene yield has been determined. A mathematical optimation method has been used for the interpretation of results. The intervals of the optimum parameters of catalyst synthesis have been established, to obtain catalyst with a high activity in low-pressure ethylene polymerization. These specified optimum parameters have been applied in the subsequent synthesis of similar catalytic systems, differing in the …
