The present invention is intended to provide a soft syndiotactic polypropylene composition having a good balance of properties such as transparency, flexibility and heat resistance and a laminate having a layer comprising the composition and a layer comprising a thermoplastic resin. The composition (1) comprises a syndiotactic propylene polymer (A), an α-olefin polymer (B), and a small amount of a crystal nucleating agent (C) and/or an ethylene-based polymer (D). The composition (2) comprises a syndiotactic propylene polymer (A), an α-olefin polymer (B), an isotactic propylene polymer (E), and a small amount of a crystal nucleating agent (C) and/or an ethylene-based polymer (D). The composition (3) comprises a syndiotactic propylene polymer (A), an α-olefin polymer (B), an isotactic propylene polymer (E), a copolymer (F) of polar group-containing vinyl and ethylene, and a small amount of an ethylene-based polymer (D).
A soft syndiotactic polypropylene composition comprising:
