Abstract:
1. A syndiotactic propylene-based polymer composition comprising 100 parts by weight of a partially cross-linked olefin-based thermoplastic elastomer composition (A) comprising a crystalline polyolefin resin (A-1) and an α-olefin-based copolymer rubber (A-2), 1 to 40 parts by weight of a syndiotactic polypropylene (B) based on 100 parts by weight of (A), and 5 to 60 parts by weight of a syndiotactic structured propylene-α-olefin copolymer (C) comprising 95 to 65 mol % of a syndiotactic structured propylene component and 5 to 35 mol % of an α-olefin (except propylene) component having 2 to 20 carbon atoms based on 100 parts by weight (A).
