Abstract
Polyolefin resin pellets of greater uniformity of shape and characterized by an almost complete absence of tails are obtained by the use in the pelletizing apparatus of dies which have been coated by a thin layer of finely divided solid lubricant such as molybdenum disulfide or, preferably, graphite applied to the interior surfaces of the die by cross bombardment with a stream or streams of finely divided solid lubricant under pressure.
