Claims
- 1. A propylene resin composition consisting essentially of the following components A, B and C in weight percentages based on the total weight of Components A, B and C:
- Component A: 50 to 80% by weight of a crystalline propylene-ethylene block copolymer having an ethylene unit content of 1 to 15% by weight, and a melt flow rate of 10 to 100 g/10 min,
- Component B: 5 to 40% by weight of an ethylene-.alpha.-olefin copolymer containing 30 to 70% by weight of an .alpha.-olefin having 4 to 18 carbon atoms, a melt flow rate of 0.01 to 7 g/10 min., and a density of 0.850 to 0.890 g/cm.sup.3, said copolymer being produced by using a metallocene catalyst,
- Component C: 1 to 30% by weight of talc having an average particle size of 0.1 to 5.mu..
- 2. A resin composition according to claim 1, wherein said component A has a ratio by weight of a crystalline phase (I) to an intermediate phase (II) within the range of 11.2 to 4, and an amorphous phase (III) content of 3 to 30% by weight, these phases being determined by Multiple-Pulse NMR Techniques.
- 3. A resin composition according to claim 1, wherein said component A has an ethylene unit content of 2 to 10% by weight, and a melt flow rate of 20 to 90 g/10 min.
- 4. A resin composition according to claim 1, wherein said component B has an .alpha.-olefin content of 30 to 65% by weight, a density of 0.855 to 0.880 g/cm.sup.3, and a melt flow rate of 0.1 to 5 g/10 min.
