Abstract
A gaseous mixture of steam and air, a gaseous mixture of steam and nitrogen, or pure steam are passed around polyolefin granules in a deodorizing apparatus. The result is that the polyolefin granules have markedly improved properties with respect to odor and taste, and these are retained in moldings produced from the granules.
