The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.

Plasticized polyolefin compositions

A high throughput method to determine an amount of a comonomer in a copolymer sample of a copolymer system comprises the steps of providing a plurality of copolymer samples; creating an array of the copolymer samples; measuring a sample complex modulus of each of the copolymer samples at a comparison phase angle; and determining the amount of a comonomer in the copolymer sample by comparing the sample complex modulus to a calibration curve, wherein the calibration curve relates a concentration of the comonomer in the copolymer sample to a complex moduli of the copolymer sample determined at the comparison phase angle. A method of determining the amount of a comonomer in both a single copolymer sample, and in a high throughput scheme using the crossover modulus is also disclosed.

High throughput property testing of olefin copolymers using rheological determinations

A composition is provided that includes a product of combining, in the presence of a free radical initiator a catalyst precursor and at least one monomer wherein the monomer and the catalyst precursor are poiymerizable by free-radical polymerization and wherein the catalyst precursor compound is represented by the formula: wherein each X is an abstractable ligand; each R, R', R&#x2033;, R&#x2032;&#x2033;, Rand Ris independently hydrogen or a hydrocarbyl group provided at least one of R, Rand R&#x2032;&#x2033; can be polymerized by a free radical initiator; and M is a Group-4-11 metal.

Polymerized catalyst composition

This invention relates to a process to polymerize olefins comprising:

Polymerization process

Copolymerization of Ni(H) or Co(II) acenaphthene diimine complexes containing olefinic substituents on aryl groups in the presence of a free radical initiator results in polymerized late transition metal catalysts which can be used for olefin polymerization or oligomerization. These catalysts have high catalyst activity for olefin polymerization or oligomerization.

Polymerization catalyst composition

Copolymerization of Ni(II) phenol imine complexes containing olefinic substituents on aryl groups with styrene in the presence of a radical initiator results in polymerized late transition metal catalysts which can be used for olefin polymerization or oligomerization. These catalysts have high catalyst activity for olefin polymerization or oligomerization.

Polymerized catalyst composition II

A blend useful as a diesel fuel, as well as a method for its production, comprising a high quality Fischer-Tropsch derived distillate boiling in the range of a diesel fuel blended with a cracked stock boiling in the range of a diesel fuel wherein the final blend contains 10-35 wt. % aromatics and 1-20 wt. % polyaromatics and produces low regulated emissions levels.

Low emissions F-T fuel/cracked stock blends

A hydrocarbon wax product from a hydrocarbon synthesis slurry comprising liquid synthesis product and catalyst particles is purified by introducing a portion of hydrocarbon synthesis slurry from a hydrocarbon synthesis zone to a treatment zone in which a treatment gas contacts the hydrocarbon synthesis slurry. Hydrogen or a hydrogen-containing gas is useful as the treatment gas. The gas treatment removes impurities from the hydrocarbon wax portion of the hydrocarbon synthesis slurry. Purified wax product is separated and removed in situ via wax withdrawal means. This avoids or minimizes the need for further treating the wax product.

Production of high purity fisher-tropsch wax

A wide cut Fischer-Tropsch derived diesel fuel is produced wherein the distillate boils in a wider range than a conventional diesel fuel while providing favorable low temperature properties and environmentally beneficial effects. In particular, the fuel comprises a hydrocarbon distillate derived from the Fischer-Tropsch process having T90 greater than 640&deg; F. (338&deg; C.) but less than 1000&deg; F. (538&deg; C.) and a cold filter plugging point less than or equal to &plus;5&deg; C.

Wide cut Fischer Tropsch diesel fuels

Clean distillate useful as a diesel fuel or diesel blending stock is produced from Fischer-Tropsch wax by separating wax into heavier and lighter fractions; further separating the lighter fraction and hydroisomerizing the heavier fraction and that portion of the light fraction below about 500&deg; F. The isomerized product is blended with the untreated portion of the lighter fraction.
