Abstract:
Polymer blends comprising at least one olefin block copolymer such as poly(ethylene-b-ethylene/propylene-b-ethylene), and at least one propylene-based elastomer such as a propylene-ethylene random copolymer, such blends useful in elastic hygiene articles. The blends have improved permanent set compared to the propylene-based elastomer alone.
