[Propylene-based block copolymer (A)]
The propylene-based block copolymer (A) is obtained by a step of producing a propylene polymer component and a step of producing a propylene-ethylene copolymer rubber component, and simultaneously satisfies the following requirements [1] to [8]. And preferably satisfies the requirement [9]. The propylene polymer is crystalline, and is a copolymer of propylene and a small amount of another α-olefin, or a propylene homopolymer.
[1] According to ASTM D1238E, the melt flow rate (MFR) measured at 230 ° C. and a load of 2.16 kg is 20 to 150 g / 10 min.
[2] It is composed of 5 to 50% by weight of a part soluble in room temperature n-decane (Dsol) and 50 to 95% by weight of a part insoluble in room temperature n-decane (Dinsol) (however, the total amount of Dsol and Dinsol) Is 100% by weight),
[3] The molecular weight distribution (Mw / Mn) of Dsol is 7.0 or more, 20 or less,
[4] The ethylene content of Dsol is 25 to 45 mol%,
[5] The intrinsic viscosity [η] of Dsol is 1.8 to 4.0 dl / g,
[6] Dinsol molecular weight distribution (Mw / Mn) is 7.0 or more and 20 or less, and Mz / Mw is 6.0 or more and 20 or less.
[7] The pentad fraction (mmmm) of Dinsol is 95% or more,
[8] In Dsol, the value of CSD defined by the following formula (i) is 1.0 to 2.0.
