A self supporting film having one or more layers wherein at least one layer has a percent haze of less than 17.8 and the polymer of that layer consists essentially of a polyethylene having a density of at least 0.925 grams per cc, a molecular weight distribution of no more than 4, optionally containing a fluoroelastomer, and methods for making such film are disclosed.

Polyethylene film

A high clarity film containing three layers wherein the polymer of each outer layer is the same or different polyethylene selected from polyethylenes having a density of at least 0.925 g/cc, and a molecular weight distribution of less than 4, and being further characterized by being substantially free of branches having 6 or more carbon atoms, polyethylenes of the outer layers optionally containing a fluoroelastomer.

Films comprising metallocene catalyzed polyethylene

An ethylene polymer composition is provided that comprises: (a) an ethylene polymer (b) a crosslinking agent; and (c) a non-aromatic, cyclic, unsaturated, crosslinking co-agent.

Ethylene polymer compositions

A composition of matter is provided comprising:

Poly(mono-1-olefin) compositions

Thermally stabilized stereoregular, branched-mono-1-olefin polymer

A process is provided comprising contacting under deodorizing conditions, at least one deodorizing composition with at least one poly(mono-1-olefin), wherein said deodorizing conditions comprise, a standard pressure from about 1 to about 5, and a standard temperature from about 0.5 to about 2.5.

Process to deodorize an odorous poly(mono-1-olefin)

An olefin polymerization catalyst prepared by reacting a metal dihalide and a transition metal, then reacting that component with a precipitating agent, and then reacting the resulting solid with an activating component, wherein multiple activation steps are used so that it is possible to obtain a given level of activity with less activating component.

Polyolefin polymerization process and catalyst

An olefin polymerization catalyst prepared by reacting water with a magnesium dihalide in the presence of a phase transfer catalyst and reacting the resulting hydrated magnesium dihalide with reactants including a benzoic acid ester, an alkoxytitanium compound, an organoaluminum halide and a titanium halide.

Hydrogenation of an acyloxyolefin is effected in the presence of at least one of an alkali and an alkaline earth metal salt of a carboxylic acid. In one embodiment, 1,4-diacetoxy-2-butene is converted to 1,4-diacetoxybutane employing potassium acetate.

Diacyloxyolefins are hydrogenated in presence of alkali and alkaline

An organic ester is produced by conversion of an organic halide employing excess alkali metal carboxylate. A resultant reaction mass including solids comprised of alkali metal halide is obtained containing occluded in the solids portion an amount of otherwise difficult-to-recover desired ester product. At least a portion of said solids is recycled to the conversion whereby to prevent further occlusion of desired product. In an embodiment of the invention, potassium acetate salt is recycled for reuse.
