    Abstract: A supported transition metal composition is obtained by suspending a support material in an inert liquid medium, spraying the suspension, collecting a solid material and contacting the sprayed solid with a transition metal compound. The support material may be a metal halide such as magnesium chloride or an inorganic oxide such as silica or alumina. In addition to being contacted with the transition metal compound, the support material may be contacted either before or after the spraying step with other reagents such as organo metallic compounds, halogen compounds, or Lewis Base compounds. The product obtained after contacting with the transition metal compound may be used as a component of a polymerization catalyst system to polymerize an unsaturated monomer such as ethylene or propylene.

    Abstract: A catalyst component is a transition metal composition which is obtained by reacting together an inert particulate material, an organic magnesium compound, a halogen-containing compound such as carbon tetrachloride or silicon tetrachloride and a specified transition metal compound. The catalyst component obtained can be used, together with an organic metal compound, to give an olefin polymerization catalyst. The catalyst can be used to effect the polymerization of olefin monomers, for example, the copolymerization of ethylene with an alpha-olefin monomer such as butene-1 in a fluidized bed reactor.

    Abstract: In accordance with one embodiment of this invention, a zerovalent chromium compound is introduced onto an activated phosphate-containing support and utilized in conjunction with an organometal cocatalyst, such as a trialkylborane. In accordance with another embodiment of this invention, a phosphate-containing xerogel is formed by removing water from an aluminum phosphate-containing hydrogen by means of azeotropic distillation or washing with a volatile, water miscible organic compound, activated and thereafter zerovalent chromium 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 zerovalent chromium compound added. The resulting catalysts are capable of giving high melt index, broad molecular weight distribution polymer, which polymer also exhibits other deviations from typical olefin polymers including lower flexural modulus. The catalyst is ideally suited for forming olefin polymers such as ethylene and ethylene copolymers in a slurry system.
