Abstract: A multilayer fluoropolymer film comprising, in order: a first layer comprising a first polymer, the first polymer comprising at least 35 mol percent tetrafluoroethylene comonomer, at least 15 mole percent vinylidene fluoride comonomer, and at least 5 mol percent hexafluoropropylene comonomer, based on the total mol percent of the first polymer; a second layer comprising a second polymer, the second polymer comprising at least 50 mol percent vinylidene fluoride comonomer, based on the total mol percent of the second polymer; and a third layer comprising a third polymer, the third polymer comprising at least 50 mol percent methylmethacrylate comonomer, based on the total mol percent of the third polymer. The multilayer fluoroplymer films are useful for example, in multi-layer film applications (e.g., traffic sign protection, commercial graphic protection, paint protection, windows, windshields, building exteriors, and photo voltaics).

Abstract: The present disclosure provides an extrudable article and a composition, each including at least one polyurethane including hydroxyl groups and latent isocyanate groups in the form of uretdione groups. The hydroxyl groups are present on a first polyurethane and the latent isocyanate groups are present on either the first polyurethane or a second polyurethane and a ratio of the latent isocyanate groups to the hydroxyl groups is greater than 1.2:1. A method of making the extrudable article is provided including reacting in an extruder a polymerizable composition including a uretdione-containing material including a reaction product of a diisocyanate reacted with itself, a hydroxyl-containing compound, and an isocyanate-containing compound. A method of making a core-sheath filament is provided including forming a core composition of the at least one polyurethane and wrapping a sheath composition including an ethylene copolymer or a polyolefin around the core composition. Further, methods of printing a composition are provided including heating and mixing the extrudable article, such as in an extruder, to form a molten composition, then dispensing the molten composition through a nozzle onto a substrate.
