ABSTRACT:
A method for extruding granular low density narrow molecular weight distribution linear ethylene polymers which comprises passing said granular polymers into an extrusion apparatus including an extruder screw, said extruder screw having a feed section wherein said polymers are introduced and thence passed through a transition section and a metering section, wherein each lead in the feed section is substantially the same and each lead in the metering section is substantially the same and wherein each lead in the feed section is 5 to 50 percent greater than each lead in the metering section.
