Abstract: Polypropylene resin compositions are provided that are useful in the production of biaxially oriented polypropylene films (BOPPs). The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP). These blends can be used to replace standard high solubles BOPP grade polypropylene homopolymers. In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends.
Abstract: Transportation fuels are provided that have reduced toxics, VOC and NOx emissions, as well as, reduced sulfur content. The transportation fuels provided meet emissions reduction requirements determined by using the EPA Complex Model and for reduced sulfur. Reduction in sulfur content allows the use of components with high concentrations of olefins, while still reducing toxics, hydrocarbon (VOCs) and NOx emissions to acceptable levels.
Abstract: Method of manufacturing inorganic polymer hybrids with improved mechanical properties and even dispersion of the inorganic material in the hybrids. Nanoscale exfoliation of inorganic materials having layered structures is induced, and said inorganic materials are combined with an emulsion comprising one or more molten polymers. The method provides nanoscale dispersion of inorganic material throughout the emulsion of one or more polymers without the use of compatibilizers.

Abstract: A process is disclosed for the catalytic hydroxylation of aromatic hydrocarbons which comprises contacting aromatic feedstock with oxidant comprising molecular oxygen, under suitable reaction conditions, in the presence of a catalyst comprising three essential components: a support; transition metal selected from the group consisting of vanadium, niobium, copper, palladium, nickel and silver, or combinations thereof, and a promoter comprising a multidentate chelating, binucleating ligand. The catalysts may further comprise additional metal ions. The process is particularly suited, for example, to the one-step conversion of benzene to phenol.
