Multilayer riblet applique and methods of producing the same are described herein. One disclosed example method includes applying a first high elongation polymer material to a web tool, where the web tool is to be provided from a first roll, and heating, via a first heating process, the first high elongation polymer material. The disclosed example method also includes applying a second high elongation polymer material to the first high elongation polymer material, and heating, via a second heating process, the second high elongation polymer material. The disclosed example method also includes applying, via a laminating roller, a support layer to the second high elongation polymer material.

A panel is configured for attachment to a mounting surface of a building structure. The panel includes a first end surface and a second end surface, spaced from each other along a longitudinal axis; a top edge surface and a bottom edge surface, spaced from each other and offset from the longitudinal axis; and an inner surface and an outer surface, opposed to each other and extending from the first end surface and the second end surface. The inner surface includes a contact portion and a contour portion. The contact portion is disposed on a reference plane. The contour portion is contoured toward the outer surface, away from the reference plane, such that the contour portion defines a channel. The channel extends along at least a portion of a length of the panel, between the first end surface and the second end surface.

A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.

A process for preparing benzoxazine-thiol polymer film is described comprising forming a rolling bank of a curable composition comprising a polybenzoxazine and a polythiol, wherein the rolling bank contacts first and second carrier substrates; passing the first and second substrates with the curable composition therebetween through a nip; and at least partially curing the curable composition to provide the corresponding polymeric layer. The compositions are useful in coating, sealants, adhesive and many other applications.
