| titleOfInvention | Process of polymerization catalyst production with controlled catalyst properties and use of same in olefin polymerizations |
| abstract | Solid catalyst components for use in olefin polymerization, olefin polymerization catalyst systems containing the solid catalyst components, methods of making the solid catalyst components and the catalyst systems, and methods of polymerizing and copolymerizing olefins involving the use of the catalyst systems. The solid catalyst components are formed by (a) dissolving a magnesium compound and an auxiliary intermediate electron donor in at least one first solvent to form a solution; (b) contacting a first titanium compound with said solution to form a precipitate of the magnesium compound and the first titanium compound; (c) washing the precipitate with a mixture of a second titanium compound and at least one second solvent and optionally an electron donor at a temperature of up to 90° C.; and (d) treating the precipitate with a mixture of a third titanium compound and at least one third solvent at 90-150° C. to form a solid catalyst component. |
