Abstract

Thermoplastic polymer blend compositions comprising an isotactic polypropylene component and an alpha-olefin and propylene copolymer, said copolymer comprising crystallizable alpha-olefin sequences. In a preferred embodiment, improved thermoplastic polymer blends are provided comprising from about 35 % to about 85 % isotactic polypropylene and from about 30 % to about 70 % of an ethylene and propylene copolymer, wherein said copolymer comprises isotactically crystallizable propylene sequences and is predominantly propylene. The resultant blends manifest compatibility characteristics, increased tensile strength, and improved process characteristics, e.g., a single melting point.
