    Abstract: Methods and apparatuses are provided for the manufacture of coextruded polymeric multilayer optical films. The multilayer optical films have an ordered arrangement of layers of two or more materials having particular layer thicknesses and a prescribed layer thickness gradient throughout the multilayer optical stack. The methods and apparatuses described allow improved control over individual layer thicknesses, layer thickness gradients, indices of refraction, interlayer adhesion, and surface characteristics of the optical films. The methods and apparatuses described are useful for making interference polarizers, mirrors, and colored films that are optically effective over diverse portions of the ultraviolet, visible, and infrared spectra.

    Abstract: A method and apparatus for the extrusion of multilayered composite products, is provided. In accordance with the inventive method, the relative orientation of a first shaped flow stream and a second shaped flow stream to one another is changed, and the reoriented shaped streams are melt-laminated to produce a layered composite formed independent of division of a layered precursor stream. Beneficially, layered flow streams that differ from one another may be used. Differences in volumetric or mass flow rates may also be used to advantage. The inventive apparatus includes a coextrusion structure and a partition member. The coextrusion structure may advantageously include one or more removably disposed, flow-shaping inserts, and the partition member may be a removably disposed, partition plate. The inventive apparatus beneficially further includes a removably disposed flow sequencer for changing the relative orientation of the flow streams.

    Abstract: Embodiments of the present invention include a novel interfacial surface generator (ISG) design comprised of helical channels and associated methods of using the new design. The novel design addresses processing challenges associated with conventional ISG designs used in layer multiplying coextrusion systems. Embodiments of the present invention may be used in either a static configuration or “active” configuration. In one active configuration, two counter-rotating cylindrical rods and/or moving belts may be used to induce drag, or Couette, flow. Conveyance of materials through the ISG may be due to pressure driven flow, drag flow, or a combination of these.

    Abstract: A multi-layer extrusion die assembly includes a body, a main bore extending longitudinally through the assembly, a core tube, and a plurality of dies. The extrusion die assembly is configured to receive an input stream of material and divide the input stream into a plurality of material streams. Each die is configured to receive one or more of the material streams and to form a single continuous layer of material about the core tube. The layer formed by each die has one or more weld lines running longitudinally along the layer. The dies are arranged along the core tube such that a plurality of concentric layers of material is formed around the core tube. Each die is rotated axially with respect to adjacent dies such that the weld lines of the layer formed by one die.
