Abstract

PURPOSE:To obtain an inorganic filler-containing propylene polymer composition having excellent scratching resistance as well as good mechanical strength and moldability, by adding an inorganic filler to a specific ethylene-propylene copolymer. CONSTITUTION:An ethylene-propylene copolymer, consisting of 90-98.5wt% practically crystalline propylene homopolymer (i) (or ethylene-propylene copolymer containing 5mol% or less ethylene unit), 5-0.5wt% practically noncrystalline ethylene-propylene copolymer containing 20-90mol% ethylene unit (ii), and 5-1wt% practically crystalline ethylene homopolymer (iii) (or ethylene-propylene copolymer containing 91mol% or more ethylene unit), is used. Namely, 50-85wt% said copolymer is mixed with 50-15wt% inorganic filler, e.g., talc or mica.
