The elongation behavior of various polymer melts extruded from the single screw extruder has been studied. Low-density polyethylene, high-density polyethylene, polypropylene, and their short glass-fiber (GF)-filled composites were used. It was found that the spinning stability was good but the drawa

Previous work by this research group has shown that the use of a lubricated skin/core flow of polymer melts and a hyperbolic converging die results in an essentially pure elongational flow a t a constant elongational strain rate in the core. The previous work was carried out on a laboratory-scale co
## Abstract A processing method based on stretching of molten polymer nanocomposites was applied to prepare dichroic films. First, dodecanethiolβcapped gold particles were embedded in low density polyethylene. The resulting isotropic films were stretched in the melt under uniaxial loading using an
