| 摘要 |
The invention relates to propylene polymer compositions comprising 45 - 79 parts per weight of a propylene homo- or copolymer, 10 - 27 parts per weight of a first elastomeric ethylene-propylene copolymer, 5 - 22 parts per weight of a second elastomeric ethylene-propylene copolymer, 1 - 15 parts per weight of an elastomeric ethylene-1-octene copolymer and 5 - 15 parts per weight of inorganic filler. The propylene polymer compositions are suitable for injection moulding of large articles, which do not show flow marks and which have a good impact strength/stiffness ratio.
