Abstract: The present disclosure relates to energy storage or collection devices and methods for making such devices having electrode materials containing exfoliated nanotubes with attached electro- or photoactive nanoscale particles or layers. The exfoliated nanotubes and attached nanoscale particles or layers may be easily fabricated by methods such as coating, solution or casting or melt extrusion to form electrodes. Electrolytes may also be used for dispersing nanotubes and also in a polymeric form to allow melt fabrication methods.

Abstract: Prepare an alkenyl-aromatic foam having good surface quality, high thermal insulating properties and low density using an extrusion method by expanding a foamable polymer composition of an alkenyl-aromatic polymer composition containing less than 20 weight-percent covalently bonded halogens and having a polydispersity of less than 2.5 and a water solubility greater than 0.09 moles per kilogram and 2.2 moles per kilogram or less at 130 degrees Celsius and 101 kilopascals pressure and 0.8-2 moles per kilogram of a blowing agent containing 0.4 moles per kilogram or more of a chlorine-free fluorinated blowing agents and water at a concentration of at least 0.22 moles per kilogram; wherein moles per kilogram are relative to kilograms of alkenyl-aromatic polymer. The resulting foam has a density of 64 kilograms per cubic meter or less and a thermal conductivity of 32 milliwatts per meter-Kelvin or less after 180 days.

Abstract: A hybrid wax compositions that are suitable for use in manufacturing wax articles (e.g., candles) by compression molding. The combination of a hydrogenated natural oil-based wax and a paraffin wax having a select distribution of hydrocarbon chain lengths provides the hybrid wax compositions with improved properties, such as improved compressive strength and improved de-molding characteristics, for example, as evidenced by reducing scarring and/or flashing. The hybrid wax compositions comprise: (a) a wax comprising a hydrogenated natural oil; and (b) a paraffin wax, wherein the paraffin wax comprises less than about 50% by weight of the hybrid wax composition, and wherein about 52% or greater of hydrocarbons in the paraffin wax have carbon chain lengths ranging from C25 to C29.

Abstract: Prepare an extruded polymeric polymer foam containing one or more thermoplastic alkenyl-aromatic polymer and one or more filler, the one or more thermoplastic alkenyl-aromatic polymer accounting for 70 weight-percent or more of all polymer components in the polymer foam, containing less than 20 weight-percent covalently bound halogen based on halogenated polymer weight and having a water solubility at 130 degrees Celsius and 101 kilopascals that is greater than 0.09 moles per kilogram of polymer and having a plurality of cells defined therein wherein the polymer foam is closed-celled, 0.5 wt % or more filler, an average cell size of 0.15 millimeters or more, a density of less than 64 kilograms per cubic meter and a unimodal cell size distribution using a blowing agent containing water at a concentration up to the water solubility of the one or more thermoplastic alkenyl-aromatic polymer.

Abstract: A polymer blend composition with a good balance of high impact resistance and moldablity with reduced tendencies of delamination in molded articles is prepared by admixing with polycarbonate a substantially linear ethylene polymer or linear ethylene polymer, and a compatibilizing graft copolymer of a styrene and acrylonitrile copolymer grafted to an ethylene, propylene, and optional diene copolymer.

Abstract: The invention provides composites of organic polymeric compositions including a matrix of an organic polymer and a filler distributed throughout the matrix, the flier being present in the matrix substantially as separate particles, each about the fundamental particle size of the filler. The fillers are unique mixed metal hydroxide compositions that are obtainable in sub-micron size particles. These particles are layered and have a BET specific surface area in excess of about 100 m.sup.2 /g. An anion of the particulates is selected to be compatible with the organic polymer thereby providing ease of dispersion of the filler particles throughout the polymer matrix.
