Formulations of solutions and processes are described to form a substrate including a dopant. In particular implementations, the dopant may include arsenic (As). In an embodiment, a dopant solution is provided that includes a solvent and a dopant. In a particular embodiment, the dopant solution may have a flashpoint that is at least approximately equal to a minimum temperature capable of causing atoms at a surface of the substrate to attach to an arsenic-containing compound of the dopant solution. In one embodiment, a number of silicon atoms at a surface of the substrate are covalently bonded to the arsenic-containing compound.

Catalyst compositions useful for the polymerization or oligomerization of olefins are disclosed. Certain of the catalyst compositions comprise N-pyrrolyl substituted nitrogen donors. Also disclosed are processes for the polymerization or oligomerization of olefins using the catalyst compositions.

Catalysts containing N-pyrrolyl substituted nitrogen donors

Improved Group 3&#x2013;11 transition metal based catalysts and processes for the polymerization of olefins are described. Some of the ligands are characterized by a preferred substitution pattern which allows for higher productivities of highly branched olefins; substitution patterns which boost productivity or alter the polymer microstructure are also described.

Productivity catalysts and microstructure control

Catalyst compositions useful for the polymerization of olefins are disclosed. These compositions comprise a Group 8-10 metal complex comprising a bidentate or variable denticity ligand comprising one or two nitrogen donor atom or atoms independently substituted by an aromatic or heteroaromatic ring(s), wherein the ortho positions of said ring(s) are substituted by aryl or heteroaryl groups. Also disclosed are processes for the polymerization of olefins using the catalyst compositions.

Catalysts containing per-ortho aryl substituted aryl or heteroaryl substituted nitrogen donors

The present invention includes novel ligands which may be utilized as part of a catalyst system. A catalyst system of the present invention is a transition metal-ligand complex. In particular, the catalyst system includes a transition metal component and a ligand component comprising a Nitrogen atom and/or functional groups comprising a Nitrogen atom, generally in the form of an imine functional group. In certain embodiments, the ligand component may further comprise a phosphorous atom. Preferred ligand components are bidentate (bind to the transition metal at two or more sites) and include a nitrogen-transition metal bond. The transition metal-ligand complex is generally cationic and associated with a weakly coordinating anion. A catalyst system of the present invention may further comprise a Lewis or Bronsted acid. The Lewis or Bronsted acid may be complexed with the ligand component of the transition metal-ligand complex.,

Methods for preparing olefin polymers, and catalysts for preparing olefin polymers are disclosed. The polymers can be prepared by contacting the corresponding monomers with a Group 8-10 transition metal catalyst and a solid support. The polymers are suitable for processing in conventional extrusion processes, and can be formed into high barrier sheets or films, or low molecular weight resins for use in synthetic waxes in wax coatings or as emulsions.
