Title: Catalyst system and process for producing a catalyst.
IPC: C08F4/62
Filed: 1983-03-29
Abstract: In accordance with one embodiment of this invention, a bis-(cyclopentadienyl)chromium(II) compound is introduced onto an activated phosphate-containing support and utilized in conjunction with an organometal cocatalyst, such as an alkylaluminum. In accordance with another embodiment of this invention, a phosphate-containing zerogel is formed by removing water from an aluminum phosphate-containing hydrogel by means of azeotropic distillation or washing with a volatile, water miscible organic compound, activated and thereafter a bis-(cyclopentadienyl)chromium(II) compound is incorporated therewith. In other embodiments of this invention, a phosphate-containing support is formed by forming aluminum phosphate from an aluminum alkoxide or from a melt, or by phosphating silica or alumina, or by forming an aluminum phosphate/silica combination. A support thus formed is activated and a bis-(cyclopentadienyl)chromium(II) compound added. Alternatively in all embodiments, the chromium and phosphate components can be added separately. The resulting catalysts are capable of giving narrow molecular weight distribution polymer because of the inherent high molecular weight of the polymer produced, and the unusual sensitivity to hydrogen, a broad spectrum of polymers can be produced so far as molecular weight is concerned. The catalyst is ideally suited for forming olefin polymers such as ethylene and ethylene copolymers in a slurry system.
