    摘要： Provided are blends of branched hydrocarbon comb polymers having tailored branching and molecular weight parameters, with substantially linear polymers. Such blends have been found to have improved extensional rheological properties, while maintaining nearly the viscosity of the substantially linear polymers. The blends of the hydrocarbon comb polymers with the substantially linear polymers thus maintain the extrusion processing characteristics of the linear polymer alone, but have improved extensional flow processability, with strain hardening ratios (SHR) greater than 1. The blends are effective in blown film processing. Also disclosed are related methods for improving extensional flow processability using the branched hydrocarbon comb polymers, as well as the branched hydrocarbon comb polymers themselves, including as a property enhancing additive for such substantially linear polymers.

    摘要： Provided are oil-in-water and water-in-oil emulsion compositions including from 0.01 to 5 wt % of a halogenated elastomer emulsifier, and optionally from to 0.5 wt % of a polyalkylene amine co-emulsifier. The emulsion compositions disclosed herein provide for increased interfacial elasticity and decreased interfacial tension at the oil-water interface to increase resistance to coalescence of dispersed water droplets of a water-in-oil emulsion or oil droplets of an oil-in-water emulsion. The emulsion compositions disclosed herein are suitable for lubricant applications due to their resistance to shear thinning.

    摘要： Polyethylene blend compositions suitable for injection molding, injection molded articles, and processes for injection molding articles are provided. The polyethylene compositions include a first polyethylene having a melt index of 0.1 to 3.0 g/10 min and a density of from 0.905 to 0.938 g/cm3; and a second polyethylene having a melt index of 10 to 500 g/10 min and a density of 0.945 to 0.975 g/cm3. The compositions have a density of from 0.920 to 0.973 g/cm3 and a melt index of 2 to 200 g/10 min, and the density of the second polyethylene is from 0.037 to 0.062 g/cm3 greater than the density of the first polyethylene. The compositions exhibit improved physical properties, such as Environmental Stress Crack Resistance, relative to conventional compositions of similar melt index and density. In certain embodiments, the compositions, and articles produced therefrom, also exhibit an improved balance of toughness properties and processability properties.
