PROBLEM TO BE SOLVED: To obtain a propylene polymer composition excellent in antistatic properties and releasability from molds by compounding a propylene polymer (A) with a dioxyethylenealkylamine antistatic agent (B) and a fatty acid monoamide (C). SOLUTION: A known propylene polymer can be used as ingredient A without any specific limitation; for example, a propylene homopolymer prepared by the polymerization catalyzed by a Ziegler catalyst or a metallocene catalyst or a copolymer of propylene and anotherα-olefin can be used, Octanoyldiethanolamine is an example of ingredient B. Ingredient C is used as a lubricant, an example being lauramide. When the composition is used under the exposure to light, a heterocyclic hindered secondary amine light stabilizer (D) may be compounded. Ingredient A in an amount of 100 pts.wt. is compounded with 0.01-1 pt.wt. ingredient B, 0.01-1 pt.wt. ingredient C, and 0.01-1 pt.wt. ingredient D.
