Improved thermoplastic polymer soft elastic fiber blend compositions including a crystalline isotactic polypropylene component and a crystallizable alpha-olefin and propylene copolymer component, the copolymer comprising crystallizable alpha-olefin sequences. In a preferred embodiment, improved thermoplastic polymer blends are provided prepared from 0% to 95%, preferably 2% to 40% of the crystalline isotactic polypropylene and from 5% to 100%, preferably 60% to 98% of a crystallizable ethylene and propylene copolymer, wherein said copolymer comprises isotactically crystallizable propylene sequences and is predominately propylene. The resultant blends manifest unexpected compatibility characteristics, increased tensile strength, and, improved resistance to elastic deformation.
