Abstract
Polymer blend compositions of a first polymer component comprising an ethylene propylene copolymer and a second polymer component comprising an isotactic polypropylene copolymer. The first polymer component has a uniform distribution of both tacticity and comonomer between copolymer chains. Further, the first polymer component will exhibit a statistically insignificant intramolecular difference of tacticity.
