Abstract: The present invention provides multiple layer interlayers that can be used in multiple layer glass panel type applications to reduce the amount of sound transmitted through the panel while also providing a colored region within a gradient region. The acoustic effect can be achieved by using two or more polymer sheets having differing compositions that have been combined into a single multiple layer interlayer, and the gradient region effect is achieved by forming a colored region in one or more gradient regions of the individual layers.

Abstract: The present invention is directed to the use of injection molding to form polymeric interlayers directly between two rigid substrates that are positioned so that after injection of the melted polymeric material and after cooling, the resulting multiple layer panel functions as a safety panel that can be used in any appropriate conventional safety glazing application. Methods of the present invention utilize a relatively low molecular weight polymer, multiple injection points, mold compression, and/or a heated substrate in order to facilitate the injection of polymer into the relatively narrow space between glazing substrates that is typically found in safety glazings.

Abstract: In preparing rough-surfaced sheet of polyvinyl butyral (PVB), a fraction of stiffly resilient particles of crosslinked PVB are present in the formulation which on exiting an extrusion die opening mechanically interfere with and roughen the surface of the sheet being formed.

Abstract: A light-transmitting laminated panel having increased resistance to impact-induced rupture sequentially includes: a) a glass layer, b) an optically clear layer of a plasticized polyvinyl butyral matrix containing discrete particles of crosslinked polyvinyl butyral integrally randomly dispersed throughout the matrix which enhance the impact-resistance of the panel and are visually indistinguishable from the matrix polyvinyl butyral, and c) another glass layer, the laminated panel at a specific pummel adhesion having greater mean break height than that of a laminated panel containing layers a), b) and c) but without the impact-resistance-enhancing particles of crosslinked polyvinyl butyral in layer b). An amount up to 40 weight % of the particles is incorporated into the matrix polyvinyl butyral before preparing the laminated panel.
