Catalyst and olefin polymerization
A polymerization catalyst providing a good balance of productivity and polymer fines prepared by reacting a metal halide, such as MgCl2, with a titanium compound, such as Ti(OEt)4, to form a first catalyst component; mixing a solution of said first catalyst component with an organoaluminum compound...

Zusammenfassung: | A polymerization catalyst providing a good balance of productivity and polymer fines prepared by reacting a metal halide, such as MgCl2, with a titanium compound, such as Ti(OEt)4, to form a first catalyst component; mixing a solution of said first catalyst component with an organoaluminum compound at a temperature in the range of -100 DEG to 70 DEG C.; then heating to a higher temperature in the range of 50 DEG C. to 110 DEG C. to form additional precipitate, and then reacting the resulting solid with a halogenating agent. |
