    摘要: In one embodiment of this invention a surface silicated alumina composition, as opposed to conventional silica alumina, is provided. Such composition may also be fluorided and/or phosphated or phosphited. The resulting compositions are broadly useful but are of particular applicability as supports for chromium olefin polymerization catalysts. In another aspect alumina is fluorided and used with hexavalent chromium catalyst and a co-catalyst or in the alternative with an organochromium catalyst. If desired the support in this embodiment can also be phosphated or phosphited. In another embodiment, aluminum phosphate is formed in the pores of alumina. In contrast with alumina catalyst supports of the prior art, the supports of this invention allow for the production of olefin polymers at high rates of productivity. Also novel high density ultrahigh molecular weight polymers are produced.

    摘要: Polymerization catalyst consisting essentially of treated silica support and zerovalent chromium compound is provided, as well as process for preparation and polymerization process with the invention catalyst. Silica treatment involves contacting a predominantly silica-containing support with at least one compound selected from the group consisting of Group IIA oxide or compounds convertible to the oxide form, a Group VA or VB oxide or compounds convertible to the oxide form or sulfuric acid, and calcining prior to contacting the treated support with a zerovalent chromium compound, thereby producing an active polymerization catalyst.
