Abstract
Official abstract text for this publication.
A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of micro- to nano-polymer layers. These new shapes contain contiguous layers of milli- to nano-polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.
First claim
Opening claim text (preview).
What is claimed is: 1. A multilayered extrusion product comprising a tubular microlayered composite, wherein said tube comprises contiguous layers without weld lines and has a shape selected from profile, polygonal, annular, diamond, rombus, pentagon, and hexagon, and wherein one or more layers of said tubular microlayered composite contain fibers or particles. 2. A multilayered extrusion product according to claim 1 , comprising two compositions wherein said tube layers of composition A and composition B alternate in a pattern A-B-A-B-A-B or A-B-B-A-B-B-A-B-B. 3. A multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular composite is hollow. 4. A multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular composite comprises a solid core. 5. A multilayered extrusion product according to claim 1 , comprising two or more compositions wherein said tubular composite comprises a skin layer.
