Abstract: The present invention is an optically transparent laminate film comprising: at least three layers of film, wherein at least two of the at least three layers comprise ionomeric films, and wherein the film can be suitable for use in a photovoltaic cell or in packaging.

Abstract: A composition and a process for blocking water in an article are disclosed. The composition can comprise or be produced from a first polymer, a second polymer, and optionally a third polymer; the first polymer comprises an ethylene copolymer comprising repeat units derived from ethylene and a polar monomer; the second polymer comprises a polyacrylic acid or its salt or its cross-linked polymer thereof, a polymethacrylic acid or its salt or cross-linked polymer thereof, or combinations of two or more thereof; and the third polymer comprises polyvinyl alcohol. The process can comprise contacting the article with the composition.

Abstract: The present invention is a film obtained from a blend of chemically distinguishable copolymers, wherein the film has a light transmission of at least 85%, and/or a haze of less than 6%, and wherein the blend comprises a component copolymer has a secant modulus of less than 15,000 when cast independently into a film.

Abstract: A multi-layer sheet and a process for producing the sheet are disclosed. The sheet can comprise a first polymer layer comprising a film of polyvinyl fluoride (PVF) or polyvinylidene fluoride (PVDF) having an adhesive coating on one side; second optionally pigmented polymer layer extruded onto the adhesive coating of the first polymer layer; and optionally a third polymer layer. Also a photovoltaic module comprising a prebonded backskin that comprises the multi-layer sheet.
