Abstract
The present invention provides a propylene polymer composition having excellent transparency, flexibility, heat resistance, scratch resistance and rubber elasticity with a good balance. The propylene polymer composition comprises 1 to 40 parts by weight of isotactic polypropylene (i) and 60 to 99 parts by weight of a propylene/ethylene/α-olefin copolymer (ii) which contains 45 to 89% by mol of a propylene component, 10 to 25% by mol of an ethylene component, and optionally, 0 to 30% by mol of constituent units (a) derived from an α-olefin of 4 to 20 carbon atoms.
