    摘要： A sound- and vibration-dampening (NVH) layered composition may be prepared by spraying or spray-foaming a polyurethane heavy layer, and spray-foaming a flexible polyurethane foam layer, under conditions such that the two layers bond integrally with one another without use of glue or other adhesive. Additional layers, that are the same as, or different from, these two layers may also be included in the composition. The layered composition may be used in, for example, automotive applications. The method is faster and requires less hardware and space than conventional methods that include gluing steps or employ heavy molds to withstand the pressures generated therein by methods such as injecting or pouring; however, it may still attain relatively uniform thicknesses even when spraying is done on a substrate that does not become part of the final construction.

    摘要： The instant invention is a high-density polyethylene composition, method of producing the same, articles made therefrom, and method of making such articles. The high-density polyethylene composition of the instant invention includes a first component, and a second component. The first component is a high molecular weight ethylene alpha-olefin copolymer having a density in the range of 0.915 to 0.940 g/cm3, and a melt index (I21.6) in the range of 0.5 to 10 g/10 minutes. The second component is a low molecular weight ethylene polymer having a density in the range of 0.965 to 0.980 g/cm3, and a melt index (I2) in the range of 50 to 1500 g/10 minutes. The high-density polyethylene composition has a melt index (I2) of at least 1, a density in the range of 0.950 to 0.960 g/cm3, and g′ of 1.

    摘要： A method and composition for forming an adhesive bond is described. The method includes depositing an aqueous dispersion on a substrate to form a selectively activatable coating, the aqueous dispersion including (A) a polymer capable of forming an adhesive, (B) at least one dispersing agent; and (C) at least one of a tackifying resin, a wax, or an oil wherein the dispersion has at least one of an average particle size of from about 0.1 to about 100 microns and a polydispersity of less than 5; and selectively activating at least a portion of the coated substrate to form the adhesive bond.
