PURPOSE:To produce a rubber-containing propylene polymer composition of improved weathering resistance, by mixing a rubber component containing a light stabilizer dispersed therein with a crystalline propylene polymer. CONSTITUTION:A rubber component (e.g., ethylene/propylene rubber) containing a light stabilizer (e.g., bis-2,2,6,6-tetramethyl-4-piperidyl sebacate) dispersed therein is mixed with a crystalline propylene polymer (e.g., propylene homopolymer or propylene/ethylene copolymer). In this way, a rubber-containing propylene polymer composition of improved weathering resistance can be obtained.
