Compositions have been created comprising a blend of a polypropylene having less than 90 percent isotactic linkages and thermoplastic block copolymers. Specifically, the thermoplastic block copolymers comprise hard segments of polystyrene combined with soft segments comprising 2 to 8 carbon atoms. Some of the physical characteristics of materials made by these composition are more desirable than the same physical characteristics of materials made of the polypropylene having less than 90 percent isotactic linkages used to make the composition and of the same physical characteristics of materials made of the thermoplastic block copolymer used to make the composition.

1. A polypropylene and thermoplastic copolymer blend consisting essentially of:(a) a homopolypropylene component comprising about 50 percent to 70 percent isotactic linkages; and (b) a thermoplastic block copolymer component comprising hard segments of polystyrene combined with soft segments including a combination of ethylene and butylene; wherein the blend is in the range of about 80 percent by weight of the homopolypropylene and about 20 percent by weight of the thermoplastic block copolymer to about 20 percent by weight of the homopolypropylene and 80 percent by weight of the thermoplastic block copolymer.
