  • Patent number: 10640672
    Abstract: The invention relates to an acrylic layer (in the form of a coating, film or sheet) useful as part of a photovoltaic module backsheet. The acrylic layer contains at least 40 percent of one or more acrylic polymers, including an acrylic polymer matrix and optionally acrylic impact modifiers. The acrylic polymer is preferably a polymer, copolymer, or terpolymer containing at least 50 weight percent of methylmethacrylate monomer units. The acrylic layer is flexible and optionally contains high levels of white pigment. It may also contain fluoropolymers such as polyvinylidene fluoride to improve weathering, processibility and film formation. The acrylic layer adheres to a polymer support layer such as polyethylene terephthalate (PET). A preferred substrate is PET that is pre-treated to improve adhesion, but unprimed PET can also be used. The backsheet provides excellent weatherability, environmental stability and reflectivity as part of a photovoltaic module.

  • Patent number: 9587100
    Abstract: The invention relates to an acrylic copolymer additive useful as a process aid in highly filled polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) composites. The acrylic additive is especially useful in highly filled PVC flooring tiles, rolled flooring, pipe and siding. The acrylic copolymer additive contains from 50 to 79 weight percent of methyl methacrylate monomer units, and has a Tg of less than 90° C.

  • Patent number: 8332554
    Abstract: In one embodiment of a networking module, a first block receives a serial digital media signal, and provides a parallel digital media signal based on the serial digital media signal. A second block, operative with the first block, stores the parallel digital media signal in a corresponding slot in an outgoing frame, and sends the outgoing frame in response to receiving an incoming frame.
