A process for incorporating a clarifying agent into a semi-crystalline polyolefin resin is provided whereby a clarifying agent selected from compounds having the formula: wherein p is 0 or 1, m and n are independently 0-3, and R is, at each occurrence, independently selected from C1-8 alkyl, C1-4 alkoxy, hydroxy, halogen, C1-6 alkylthio, C1-6 alkylsulfoxy and a 4 or 5 membered alkyl group forming a carbocyclic ring wi th adjacent carbon atoms of the unsaturated parent ring, and wherein the clarifying agen t is in the form of a powder characterized by a d97 of 30 microns or less, and a mean particle size of 15 microns or less, is blended with the polyolefin resin, at a temperatur e above 170.degree.C until the clarifying agent is dissolved in the molten resin.
