Abstract: A polymer interlayer with improved acoustic properties. The polymer interlayer comprises a first polymer layer, a second polymer layer, and a third polymer layer. The first polymer layer is positioned between the second polymer layer and the third polymer layer. The first polymer layer is formed from a resin comprising polyvinyl acetate (PVAc). The first polymer layer has a Tg of less than about 20° C. and a peak tan δ greater than about 2.0.

Abstract: A polymer interlayer that resists formation of optical defects. The polymer interlayer comprises a first polymer layer, a second polymer layer, and a third polymer layer. The first polymer layer is positioned between the second polymer layer and the third polymer layer. The first polymer layer has a glass transition temperature of less than about 20° C. and the second and third polymer layers each have a glass transition temperature of more than about 25° C. The polymer interlayer has an edge. The first polymer layer is not present within a portion of the polymer interlayer. The portion of the polymer interlayer extends a distance X from the edge of the polymer interlayer, with the distance X being between 0.2 and 40 cm.

Abstract: Processes are disclosed for recovering stiff poly(vinyl butyral) from a plasticized poly(vinyl butyral) multilayer sheet containing the stiff poly(vinyl butyral) and soft poly(vinyl butyral). The processes include grinding the plasticized poly(vinyl butyral) multilayer sheet to obtain a granulate; adding additional plasticizer to the granulate to remove at least a portion of the soft poly(vinyl butyral); and physically separating the granulate from the resulting solution.

Abstract: Display systems and methods are disclosed for displaying images, while preventing or reducing unintended viewing. A projector is provided that emits light toward a viewing surface at three discrete wavelength ranges to create an image. A light-absorbing substrate is also provided, disposed between the viewing surface and the unintended viewer, incorporating narrow-band absorbers that selectively absorb light within the three wavelength ranges, thus reducing or eliminating the image perceived by the unintended viewer.

Abstract: Interlayers that exhibit superior properties and that provide desirable optical properties when incorporated into laminates, such as windshields, windows or other glazings containing a holographic optical element (HOE) are disclosed. The interlayers, when used in a laminate in conjunction with the HOE film, maintain and do not detract from the HOE film properties.
