A process to produce a multicomponent ethylene polymer composition is provided. This process comprises: (a) contacting an organic peroxide with at least one post consumer ethylene polymer resin that has a density from about 0.95 to 0.97 grams per cubic centimeter and a melt index from about 0.3 to about 1 gram per ten minutes; and thereafter (b) blending the composition formed in (a) with at least one virgin ethylene polymer resin that has a density from about 0.93 to 0.945 grams per cubic centimeter and a melt index from about 0.01 to about 0.16 grams per ten minutes.

Process to produce a multicomponent ethylene polymer composition

This invention relates to deodorizing odorous polyolefins. This is accomplished by mixing the odorous polyolefin with low concentration levels of an inorganic oxidant. Optionally, a fragrance is mixed with the odorous polyolefin mixture. Additionally, if desired, heat can be applied to the mixture.

A process for the separation of isomeric cresols includes the step of crystallizing from a medium containing phenolic and solvent components.

Isomer separation

Olefin polymerization catalyst can be obtained by mixing a transition metal compound (e.g. TiCl.sub.3) and an adjuvant selected from specific hindered phenols, esters of thiodialkanoic acids, esters of phosphorous acid and esters of phosphoric acid; the adjuvants are compatible with FDA regulations for food.

Olefin polymerization with catalysts containing food grade additives

Polymerization catalyst preparation comprising milling magnesium metal, an organic halide and titanium tetrahalide in the presence of a triaryl phosphite and an aluminum trihalide but in the absence of a complexing diluent. The titanium catalyst component is activated with an organoaluminum activator producing a catalyst for olefin polymerization. In one embodiment, the titanium catalyst component is milled in the presence of magnesium oxide. In another embodiment, the milled titanium catalyst component is subjected to heat treatment.

The octane quality of a fuel for an internal combustion engine is improved by mixing halogenated substituted fulvenes with the fuel for an internal combustion engine.

Halogenated substituted fulvenes useful as fuel antiknock additives

A catalyst system is made up of a catalyst and a cocatalyst. The catalyst component comprises a magnesium chloride support, a titanium trichloride, an aluminum trichloride and an organic phosphite. The cocatalyst comprises an organoaluminum compound. Exemplary of such a system is a MgCl.sub.2 supported TiCl.sub.3.1/3AlCl.sub.3 plus triphenyl phosphite as the catalyst and triethylaluminum plus diethylaluminum chloride and ethyl anisate as the cocatalyst. Such catalyst systems give both high productivity and low solubles in the polymerization of propylene. For ethylene polymerization, the cocatalyst can simply be triethylaluminum.

Stable low freeze point fertilizer solutions containing nitrogen, and sulfur are disclosed. The solutions contain specified ratios of ammonium nitrate, urea, and ammonium sulfate; such that the solutions are storage stable.

Fertilizer solutions containing sulfur and having low crystallization

A catalyst system is made up of a catalyst and a cocatalyst. The catalyst component is made by intensely mixing a titanium trihalide component with triaryl phosphite and aluminum trihalide adjuvants. The cocatalyst is an organoaluminum compound. An example of such a system is a ball milled mixture of TiCl.sub.3..sup.1/ 3AlCl.sub.3, triphenyl phosphite, and aluminum trichloride as the catalyst and diethylaluminum chloride as the cocatalyst. Such catalyst systems give both high productivity and low solubles in the polymerization of propylene. The catalytic activity and/or stereospecificity of the catalyst can be enhanced by heat treatment at a moderate temperature subsequent to milling the mixture.
