    摘要: A multi-modal polymer blend for use in an adhesive composition comprising at least two compositionally different propylene-based polymers. The multi-modal polymer blend has a Mw of about 10,000 g/mol to about 150,000 g/mol. When subjected to Temperature Rising Elution Fractionation, the multi-modal polymer blend exhibits a first fraction that is soluble at −15° C. in a hydrocarbon solvent, such as xylene or ortho-dichlorobenzene, the first fraction having an isotactic (mm) triad tacticity of about 70 mol % to about 90 mol %; and a second fraction that is insoluble or less soluble than the first fraction at −15° C. in the hydrocarbon solvent, the second fraction having an isotactic (mm) triad tacticity of about 85 mol % to about 98 mol %.

    摘要: A diesel fuel additive composition, a fuel containing the fuel additive, a method for improving diesel engine performance using the additive and a method for making the additive for diesel engines having a high pressure fuel injection system. The fuel additive has a number average molecular weight (Mn) of from about 500 to about 10,000 and is selected from a hydrocarbyl-substituted succinic acid or anhydride or derivative thereof and a hydrocarbyl-substituted Mannich base. The additive has a molecular weight distribution such that less than about 25 wt. % of the additive has a molecular weight of 400 or less as measured by gel permeation chromatography (GPC) based on a polystyrene calibration curve.

    摘要: Polymer fractions such as polyethylene fractions can be produced that have a PDI less than about 2.3 and a Mw greater than about 1,000,000 g/mol, 3,000,000 g/mol, or 6,000,000 g/mol. Such polyethylene fractions are separated from a UHMWPE parent polymer by first dissolving the parent polymer in a relatively good solvent. The conditions employed for such dissolution are selected to reduce the degradation of the parent polymer. The resulting parent solution is transported into a fractionation column in which a support is disposed. The fractionation column is thereafter operated at conditions effective to form a precipitate on the support comprising the desired polyethylene fraction. The polyethylene fraction may then be recovered from the fractionation column by repeatedly displacing a solvent/non-solvent mixture into the column to dissolve the polyethylene fraction. The relative concentrations of the solvent and the non-solvent are based on a solvent gradient profile of the polyethylene parent polymer.
