Title:
FLEXIBLE SYNDIOTACTIC POLYPROPYLENE COMPOSITION AND MOLDING COMPOSED OF THE COMPOSITION
Document Type and Number:
Japanese Patent JP2003049031
Kind Code:
A
Abstract:
To obtain a flexible syndiotactic polypropylene composition having excellent transparency, flexibility, impact resistance and moldability, and to provide a molding composed of the composition.
The flexible syndiotactic polypropylene composition comprises (A) a syndiotactic propylene polymer having 90-100 mol% propylene unit content, (B) a syndiotactic/propylene/ethylene copolymer having 89-65 mol% propylene unit content, (C) an isotactic propylene polymer having 90-100 mol% propylene unit content, (D) an ethylene homopolymer having a melt tension (MT (g)) at 190°C and a melt flow rate (MFR (g/10 minutes)) satisfying a relation represented by 9.0×MFR-0.65>MT>2.2×MFR-0.84 and (E) a copolymer of ethylene and a 40-20C α-olefin.
