Retreating comminuted olefin polymerization catalyst with a titanium(IV) compound, a haloalkylchlorosilane and an ester |
| abstract |
A comminuted, supported polymerization catalyst for alpha-olefins comprises (A) an organoaluminum compound and (B) a solid titanium-containing component formed by (1) comminuting a solid reaction product comprising (a) at least one halogen-containing compound of titanium(IV); (b) at least one electron donor; and (c) at least one hydrocarbon-insoluble magnesium-containing compound; and (2) retreating such comminuted product with (a) at least one halogen-containing compound of titanium(IV); (b) at least one haloalkylchlorosilane; and (c) at least one organic acid ester. |
