    摘要： An olefin polymerisation titanium catalyst. It comprises a titanium compounds and an organoaluminium compound cocatalyst supported on a soluble polysulfone comprising free reactive sulfone groups. The molar ratio of titanium to aluminium is 1-10:200 and the weight ratio of titanium to polysulfone is 0.01-0.1:0.3-2.5. The process for preparing the catalyst comprises preparing a supported titanium compound by contacting a solution of a polysulfone in a halogenated or polar solvent with a titanium compound or a solution thereof in a halogenated or polar solvent in an inert atmosphere at a temperature between 10° C. and the boiling point of the solvent such that the weight ratio of titanium to polysulfone is 0.01-0.1:0.3-2.5. The supported titanium compound is mixed with an organoaluminium cocatalyst such that the molar ratio of titanium to aluminium is 1-10:200.

    摘要： Processes for the formulation of Ziegler-type catalysts from a plurality of catalyst components including transition metal, organosilicon electron donor, and organoaluminum co-catalyst components. The components are mixed together in the course of formulating the Ziegler-type catalyst to be charged to an olefin polymerization reactor. Several orders of addition of the catalyst components can be used in formulating the Ziegler catalyst. One involves mixing of the transition metal component with the organoaluminum co-catalyst to formulate a mixture having an aluminum/transition metal mole ratio of at least 200. This mixture is combined with the organosilicon electron donor component to produce a Ziegler-type catalyst formulation having an aluminum/silicon mole ratio of no more than 50. There may be an initial pre-polymerization of the catalyst prior to introducing the catalyst into an olefin polymerization reactor. The mole ratio of aluminum to silicon in the catalyst formulation within the range of 20 to 50 and the mole ratio of silicon to transition metal within the range of 10-20. Relatively short time sequences can be used in formulating the Ziegler-type catalyst. Another order of addition involves initial contact of the organoaluminum co-catalyst and the organosilicon electron donor to provide a mixture having an aluminum to silicon mole ratio of at least 10. This mixture is then combined with the transition metal component having an aluminum/transition metal mole ratio of at least 200.

    摘要： High bulk density powders of normally solid, olefin polymers such as polyethylene are provided by polymerizing the olefin under low pressures ranging from about 5 to about 30 atmospheres in the presence of trialkyl aluminum and a titanium-containing catalyst component which has been prepared from titanium tetrachloride and diethyl aluminum monochloride. High bulk density powders prepared in accordance with the present invention can be employed directly in extrusion and other fabrication operations.
