PROCESS FOR SUBSTANTIALLY ELIMINATING SURFACE MELT FRACTURE WHEN EXTRUDING ETHYLENE POLYMERS

摘要

PROCESS FOR SUBSTANTIALLY ELIMINATING SURFACE MELT FRACTURE WHEN EXTRUDING ETHYLENE POLYMERS A process for substantially eliminating surface melt fracture during extrusion of an ethylene polymer wherein the die land has a surface fabricated from a material which increases adhesion between the die land surface and the polymer.
