    Abstract: The invention provides a weatherable composite including a moisture barrier system having a moisture vapor transmission rate at or below 1×10−2 g/m2/day, at least one weatherable layer or coating, and a substrate that is disposed between the moisture barrier system and the weatherable layer or coating. The weatherable composite may be adhered to one or both sides (e.g., front and back) of a photovoltaic thin-film cell or organic light emitting diode such that the weatherable layer(s) or coating side(s) of the weatherable composite is exposed to the environment. The weatherable composite protects the device from both moisture and UV exposure.

    Abstract: The invention relates to blends containing polymers of vinylidene fluoride, having low ductile-brittle transition temperatures and having excellent low temperature impact properties while maintaining the positive aspects of unmodified vinylidene fluoride-containing polymers. The blends of this invention are produced by adding a core-shell impact modifier (CSIM) comprised of a polysiloxane core and a shell compatible with vinylidene fluoride-containing polymer. The blends are further characterized by the presence of a heterogeneous copolymer composition comprised of two or more distinct phases and/or at least one flame and smoke suppressant. The preparation of these new blends can be done by conventional thermoplastic compounding techniques such as twin screw compounding; alternatively, the CSIM can be introduced earlier, such as in the latex. The unique properties of the new blends make them useful in end-use applications where those properties provide performance advantages, such as in wires & cables and in oil and gas applications.
