This disclosure describes co-extruded multilayer articles including at least one continuous layer and one discontinuous layer, as well as systems and techniques for the manufacture of co-extruded multilayer articles. For example, a co-extruded multilayer article is described that includes a body having a plurality of layers, where a first layer of the plurality of layers is formed from a first material and is continuous along a longitudinal axis of the body, and a second layer of the plurality of layers is formed from a second material and is discontinuously co-extruded along the longitudinal axis.

Co-extruded multilayer articles including continuous layer and discontinuous layer

A fluoropolymer coating composition is described comprising an aqueous liquid medium, fluoropolymer particles dispersed in the aqueous liquid medium, and at least one aziridine compound. The aziridine compound comprises at least two aziridine groups (i.e. polyaziridine) or at least one aziridine group and at least one alkoxy silane group. In another embodiment, an article is described comprising a substrate wherein a surface of the substrate comprises a coating comprising fluoropolymer particles; and a reaction product of at least one aziridine compound comprising at least two aziridine groups or at least one aziridine group and at least one alkoxy silane group. The coating can be utilized as a primer for bonding a non-fluorinated substrate to a fluoropolymer film and/or the coating can be used as an (e.g. outer exposed) surface layer. In some embodiments, the article may be the (e.g. backside) film of a photovoltaic module.

Fluoropolymer coatings comprising aziridine compounds and non-fluorinated polymer

A light control film includes a plurality of spaced apart substantially parallel first light absorbing regions arranged along a first direction, each first light absorbing region having a width and a height, the plurality of first light absorbing regions including nonoverlapping first and second sub-pluralities of the plurality of first light absorbing regions, the first sub-plurality of the plurality of first light absorbing regions having a first viewing angle, the second sub-plurality of the plurality of first light absorbing regions having a different second viewing angle.

A polymer composition includes a non-fluorinated, thermoplastic polymer and a minor amount of a fluoropolymer combined with the non-fluorinated polymer. A polymer processing additive composition that includes a fluoropolymer and a polymer processing additive synergist is also disclosed. The fluoropolymer includes diads represented by formula &#x2014;CF2-CF(R)&#x2014;CH(R')&#x2014;CF(R&#x2033;)&#x2014; in a range from about 23 mole percent to about 50 mole percent. Each R is independently &#x2014;CF, &#x2014;Rf, or &#x2014;ORf, each R&#x2032; and R&#x2033; are independently H, F, CF, or &#x2014;Rf, and each Rf is independently a perfluoroalkyl group having from 1 to 12 carbon atoms and optionally interrupted by one or more &#x2014;O&#x2014; groups. A method of reducing melt defects during the extrusion of a polymer is also disclosed.

Polyester polymers are described comprising polymerized units comprising a hydroxy functional aromatic group wherein the hydroxy group has been functionalized with an adhesion promoting group. In some embodiments, the polyester polymer comprises polymerized units have the general structure (A) wherein Land Lare independently divalent linking groups comprising an ester group; and Ris an adhesion promoting group bonded to the oxygen atom by means of an ionic or covalent bond. In other embodiments, film articles, laminates are described and methods of making functionalized polyester polymers are described. 

Functionalized polyester polymers and film articles

Tetrafluoroethene-based fluoropolymers of low gel content, methods of making the fluoropolymers, methods of extruding the fluoropolymers into articles, and extruded articles comprising the fluoropolymers.

Semi-fluorinated thermoplastic resins with low gel content

Presently described are methods of making coating comprising aqueous fluoropolymer latex dispersions, aqueous fluoropolymer coating compositions, coated substrates, and (e.g. backside) films of photovoltaic cells. In one embodiment, the film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; inorganic oxide nanoparticles; and a compound that reacts with the repeat units derived from VF and VDF to crosslink the fluoropolymer and/or couple the fluoropolymer to the inorganic oxide nanoparticles. In another embodiment, the backside film comprises at least one fluoropolymer comprising repeat units derived from VF, VDF, or a combination thereof; and an amino-substituted organosilane ester or ester equivalent crosslinking compound.

Fluoropolymer coatings suitable for films of photovoltaic modules

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 &#x2212;15 J/g to about 5 J/g measured from the endpoint of the glass transition (Tg) up to 230&#xb0; 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&#xb0; C. and 85% relative humidity, does not result in exfoliation or visible cracks in the PET film.
