| titleOfInvention | Propylene-based resin composition and foam obtained therefrom |
| abstract | An object of the present invention is to provide a foam sheet or film having excellent transparency, excellent balance between transparency and reflectivity, and a smaller foam cell diameter. The syndiotactic propylene polymer (A) is 100 to 50 parts by weight and the propylene / α-olefin copolymer (B) is 0 to 50 parts by weight [provided that the total of (A) and (B) is 100 Propylene-based resin composition comprising (part by weight). Here, (A) is a propylene-based polymer containing 90 to 100 mol% of propylene units and 0 to 10 mol% of one or more units selected from ethylene and an α-olefin having 4 to 20 carbon atoms (however, 100 mol%) satisfying the following requirements [1] to [3], and [1] the fraction (rrrr) measured by 13 C-NMR is 85% or more. [2] Melting point (Tm) is 145 ° C. or higher and heat of fusion (ΔH) is 40 mJ / mg or higher. [3] The intrinsic viscosity ([η], unit dL / g) at 135 ° C. and the melt tension (MT, unit mN) at 230 ° C. satisfy the following relational expression (Eq-1). 0.25 × [η] 4.8 ≦ MT ≦ 2.00 × [η] 4.8 ---- (Eq-1) (B) is a propylene polymer containing 50 mol% to 100 mol% of propylene units and 0 to 50 mol% of one or more units selected from ethylene and an α-olefin having 4 to 20 carbon atoms (provided that 100 mol in total) %). [Selection figure] None |
