Document Type and Number:
Japanese Patent JP4777343
Kind Code:
B2
Abstract:
A propylene-based polymer composition for adhesive use and a laminate structure thereof are provided, wherein decrease of bonding strength is prevented when the laminate structure is formed and heat treatment is applied and whitening in bending process is suppressed. Provided are a propylene-based polymer composition (D) for adhesive use comprising (i) 40 to 92 wt% of a graft-modified polypropylene (A); (ii) 5 to 30 wt% of an ethylene · ±-olefin copolymer (B) having a melt flow rate (MFR) of 0.01 to 10 g/10 min at 230°C under a load of 2.16 kg and a density of 0.940 g/cm 3 or less; and (iii) 3 to 30 wt% of a block copolymer (C) composed of an olefin crystalline segment and an ethylene · ±-olefin segment, wherein the sum of (A), (B) and (C) is 100 wt%, and a laminate comprising at least one layer of the propylene-based polymer composition for adhesive use.
