Abstract: The invention relates to a method for producing linear butenes from methanol. The problem addressed is that of specifying such a method in which the methanol used is converted, to the largest possible extent, into butenes. The problem is solved by combining a methanol-to-propylene process with a metathesis reaction by means of which the propene obtained from the methanol is converted into linear butenes.

Abstract: The present invention provides polymers of ethylene having ethyl branches, a narrow molecular weight distribution, no substantial amount of branches longer than any comonomer employed in the polymerization, and an unusually low branching to density ratio. In one embodiment the polyethylenes are substantially free of any branches having more than 2 carbon atoms, i.e. ethyl branches, and the molar percent of ethyl branches is substantially the same for molecular fractions across the molecular weight distribution. In another embodiment the polyethylenes have other branches having 3 or more carbons and the molar percent of the ethyl branches is substantially the same for molecular fractions across the molecular weight distribution.

Abstract: Novel chromium-containing compounds, such as, for example, chromium pyrrolides, are prepared by forming a mixture of a chromium salt, a metal amide, and an electron pair donor solvent, such as, for example, an ether. These novel chromium-containing, or chromium pyrrolide, compounds can be used either unsupported or supported on an inorganic oxide support, with a metal alkyl and an unsaturated hydrocarbon, to trimerize, oligomerize, and/or polymerize olefins.

Abstract: Novel chromium-containing compounds are prepared by forming a mixture of a chromium salt, a metal amide, and an ether. These novel chromium-containing, or chromium pyrrolide, compounds, with a metal alkyl and an unsaturated hydrocarbon, can be used as a cocatalyst system in the presence of an olefin polymerization catalyst system to produce a comonomer in-situ. The resultant polymer, although produced from predominately one monomer, has characteristics of a copolymer.
