Patent number: 4605638Abstract: There is disclosed a highly active catalyst composition for polymerizing alpha-olefins prepared by treating a support with an organomagnesium composition and contacting the thus formed solid support, containing magnesium, in a liquid medium with a transition metal compound, e.g., a tetravalent titanium compound. This catalyst is particularly useful for the production of linear low density polyethylene polymers. Also disclosed are methods of preparing polymers with the catalyst composition and the resulting polymers.Type: GrantFiled: July 24, 1984Date of Patent: August 12, 1986Assignee: Mobil Oil CorporationInventors: Thomas E.

Patent number: 4568658Abstract: A catalyst composition for polymerizing alpha-olefins in a gas phase continuous process is prepared by combining a catalyst precursor with a catalyst activator in such proportions that the polymer product comprises about 9.times.10.sup.-7 to about 18.times.10.sup.-7 gram-moles of the activator per gram of the polymer produced. The use of the activator in these proportions lowers the partial pressure of the monomers used in the process without sacrificing quality of the product. The catalyst precursor is prepared by reacting a carrier having OH groups with a stoichiometric excess, with respect to the OH groups, of an organomagnesium composition, and subsequently reacting the product with a transition metal compound.Type: GrantFiled: September 5, 1984Date of Patent: February 4, 1986Assignee: Mobil Oil CorporationInventors: John E. Cook, Thomas J. Giacobbe, Robert O. Hagerty

Patent number: RE33683Abstract: A catalyst composition for polymerizing alpha-olefins is prepared by reacting a transition metal compound, e.g., titanium, with trimethylaluminum catalyst activator. In a preferred embodiment, the catalyst is supported on a porous refractory support and is prepared by additionally reacting a magnesium compound or an organomagnesium composition with the support.Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalyst of the invention. The polymer products have higher bulk density and produce films of greater strength than polymers prepared with similar catalysts utilizing different alkyl-aluminum activators, e.g., triethylaluminum and triisobutylaluminum.Type: GrantFiled: May 26, 1989Date of Patent: September 3, 1991Assignee: Mobil Oil CorporationInventors: Louanne M.
