摘要: A catalyst support based on aluminum polyphosphate or polyphosphoric acid-impregnated alumina is provided by two alternative techniques. In the first embodiment, an aluminum polyphosphate composition is heated in a dry atmosphere and thereafter impregnated with a zerovalent chromium component under anhydrous conditions. The resulting catalyst is active for olefin polymerization. In the second embodiment, alumina is impregnated with a polyphosphoric acid composition. This resulting polyphosphoric acid impregnated alumina can be used as a support for zerovalent chromium or can be impregnated with a chromium component and oxidized to give an active hexavalent chromium species. The resulting catalysts are advantageous because of their unusual sensitivity to hydrogen thus allowing great leeway in molecular weight control.

摘要: In accordance with one embodiment of this invention, a chromium catalyst supported on an aluminum phosphate-containing base is used in conjunction with a boron component either as a part of the base or as a cocatalyst. The resulting catalyst is unique both in its favorable sensitivity to molecular weight control agents such as hydrogen and in its ability to produce a fundamentally different olefin polymer. In accordance with another embodiment of this invention, the chromium is supported on a phosphate base produced using a melt of the aluminum salt.

摘要: In one embodiment of this invention, a chromium component is supported on a silica/aluminum orthophosphate combination and used with an organometal cocatalyst. In accordance with other embodiments of the invention, the silica/phosphate combination for a chromium catalyst support is produced by either impregnating a silica xerogel with aluminum phosphate or boron phosphate, precipitating aluminum phosphate in the presence of a silica hydrogel, or physically mixing silica and aluminum phosphate xerogels. The resulting catalysts are capable of producing high melt flow olefin polymers and exhibit high activity. The resulting polymers have many unusual and desirable characteristics, such as high density and good environmental stress crack resistance.
