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
## Abstract Melt spinning experiments were carried out to investigate the elongational behavior and fiber morphology of multiphase polymer systems. Materials chosen for study were blends of calcium carbonateβfilled polypropylene with generalβpurpose polystyrene and blends of calcium carbonateβfille
