Abstract
An inexpensive yet reliable method for incorporating a minor fraction of a percent by weight of nucleating agent in a propylene polymer is provided in which the nucleating agent is dissolved at a concentration of less than 10% in a homogeneous, alcohol-based, carrier liquid having a normal boiling point of not over about 120.degree. C. The resultant solution is atomized into a full jet spray of fine droplets which is directed with full and even coverage onto a loose pulverulent bed of propylene polymer powder over a period of time and with sufficient agitation of said bed to expose essentially all segments of the bed to direct contact with said spray.
