The capillary flow of molten polymers has received much attention because at high flow rates the extrusion of the polymer melt is commonly accompanied by instabilities. These manifest themselves as surface distortions, called melt fracture, in the final plastic product. We have modeled this flow, in
The characteristics of the interface between immiscible polymers, semicrystalline polyethylene (PE) and amorphous deuterated polystyrene (dPS), were determined in the melt state, using the neutron reflectivity technique. The neutron reflectivity profiles of PE-dPS bilayer samples were measured in si
