Abstract: Provided herein are metallocene-catalyzed polyethylene compositions that exhibit a high degree of broad orthogonal composition distribution (“BOCD”), meaning that they have a relatively high degree of short-chain branching in higher-molecular-weight chains, as compared to the short-chain branching in lower-molecular weight chains. The compositions may have 80 to 99.9 wt % units derived from ethylene and 0.1 to 20 wt % units derived from a C3 to C40 ?-olefin comonomer; density from 0.925 to 0.950 g/cm3, melt index (I2.16) within the range from 0.1 to 5 g/10 min, and molecular weight distribution (Mw/Mn) within the range from 4.0 to 8.0.

Abstract: Provided herein are polymer compositions comprising a polymer and polymer processing aid (PPA) comprising a blend of at least two of: (i) a polyethylene glycol; (ii) a surfactant comprising a sorbitan ester or a polysorbate; and (iii) a metal salt of a fatty acid. The polymer can be a C2-C6 olefin homopolymer or a copolymer of two or more C2-C20 ?-olefins, and the polymer composition can take the form of polymer pellets; a polymer melt; reactor-grade polymer granules and/or polymer slurries; or other form of polymer composition containing the PPA and optionally one or more other additives. The polymer composition is preferably free or substantially free of fluorine, including fluoropolymer-based PPAs.

Abstract: Provided herein are polymer compositions and methods of making them, including blending a polymer and a polyethylene glycol (PEG) masterbatch. The PEG masterbatch can include one or more PEGs each having molecular weight less than 40,000 g/mol. The polymer can be a C2-C6 olefin homopolymer or a copolymer of two or more C2-C20 ?-olefins. The PEG masterbatch and resulting polymer composition is preferably free or substantially free of fluorine, including fluoropolymer-based PPAs.

Abstract: A film assembly for transferring an image to a surface includes a base layer, an ink layer that is removably adhered to the base layer, a developer layer that develops the ink layer and a transfer layer that is removably adhered to the developer layer, the transfer layer including the image that is configured to be transferred onto the surface. The base layer and the rear layer can be adhered together to form a rear layer. A frame layer can be removably adhered to the transfer layer. The ink layer can contain a non-toxic ink. The transfer layer can be manufactured with resilient materials. The frame layer can be removed from the transfer layer. The rear layer can be removed from the developer layer. The film assembly can be within a film assembly array of a plurality of film assemblies and can be disposed within a film assembly housing.

Abstract: A cast film is made from at least one ethylene polymer which comprises from 75.0 mol % to 100.0 mol % of ethylene derived units and which has a density of from 0.900 g/cm3 to 0.926 g/cm3, a melt index (I2.16) from greater than 1.2 g/10 min to 6 g/10 min, a melt index ratio (I21.6/I2.16) of from 20 to 50, and a z-average molecular weight (Mz) of greater 150,000 g/mol. The cast film has an average flex crack resistance as measured by ASTM F392 of less than or equal to 15 holes/300 cm2 after 10,000 cycles, preferably 8±1 holes/300 cm2 after 10,000 cycles.

Abstract: A system and method for systematically generating potential metal-organic framework (MOFs) structures given an input library of building blocks is provided herein. One or more material properties of the potential MOFs are evaluated using computational simulations. A range of material properties (surface area, pore volume, pore size distribution, powder x-ray diffraction pattern, methane adsorption capability, and the like) can be estimated, and in doing so, illuminate unidentified structure-property relationships that may only have been recognized by taking a global view of MOF structures. In addition to identifying structure-property relationships, this systematic approach to identify the MOFs of interest is used to identify one or more MOFs that may be useful for high pressure methane storage.

Abstract: A saw guide system for securing a panel and providing a guide for a saw to cut a straight line across the panel includes a sawhorse being positioned on a support surface. A first rail is coupled to a top plate of the sawhorse. The first rail supports the panel when the panel is positioned on the sawhorse. A support mount is attached to the first rail. A second rail is pivotally coupled to the first rail by the support mount. The second rail is vertically spaced from the first rail to allow the panel to be placed on the first rail. The second rail is pivoted towards the first rail to position the panel between the second rail and the first rail. The second rail is abutted by a saw to maintain a straight cut across the panel when the saw is used to cut the panel.
