Abstract: Curable compositions are provided which comprise: a) 30-80 wt % of a room temperature liquid epoxy resin; b) 0.5-10 wt % of an epoxy curative; c) 5-40 wt % of a thermoplastic resin; and d) 0.5-10 wt % of a physical blowing agent. In some embodiments, the curable compositions may be fire retardant. In some embodiments, the curable compositions may be used in the form of films, and more particularly as core splice film adhesives.

Abstract: Flame retardant adhesive are described. The flame retardant adhesives include at least 93 wt. % an acrylic copolymer. This acrylic copolymer comprises the polymerization reaction product of 50 to 92 wt. % of at least one alkyl (meth)acrylate monomer, 3 to 25 wt. % of at least one nitrogen-containing monomer, and 5 to 25 wt. % of at least one vinyl-functional poly(methacrylate) macromer. Articles incorporating such adhesive are also described.

Abstract: A solar panel backside film used in solar panel constructions. The film comprises a PET film having a net peak area as measured by differential scanning calorimetry of about ?15 J/g to about 5 J/g measured from the endpoint of the glass transition (Tg) up to 230° C., and an additive to opacify the PET film. A polymeric layer is adhered to the PET film to create a solar panel backside film. The solar panel backside film generally has a reflectivity of 50% or greater at a point in the visible range of light. Additionally, the solar panel backside film, when applied to a solar panel and exposed to 2000 hours at 85° C. and 85% relative humidity, does not result in exfoliation or visible cracks in the PET film.

Abstract: Pressure sensitive adhesive tapes having flame retarding properties include a backing and a pressure sensitive adhesive layer. The pressure sensitive adhesive layer includes a (meth)acrylate-based block copolymer, and may also include at least 10% by weight of a halogen-free flame retarding agent. The adhesive layer may contain additional optional additives such as tackifying resins, plasticizers, and the like. The tapes are prepared by coating the flame retarding pressure sensitive adhesive onto the backing, either in solvent or by a solventless process.

Abstract: A process for the preparation of a 3-alkylated indole, which comprises:a) reacting a N-(2-nitrostyryl) enamine with an alkylating agent to afford an imine salt,b) optionally reacting the imine salt with water to afford a (2-nitrophenyl)acetaldehyde, andc) reacting the imine salt or the (2-nitrophenyl)acetaldehyde with a reducing agent capable of selectively reducing the nitro group, to afford the desired 3-alkylated indole.

Abstract: A laminated window for a vehicle, for example a windshield, has electrical conductors carried between the plastics interlayer and one of the glass sheets. An obscuration band is fired on to the margin of the inner surface of the outer glass sheet, which obscures from external view conductive strips near the edges of the window.
