Abstract
Polymer blends comprise at least one ethylene/α-olefin interpolymer and one or more oil. The oil can be an aromatic oil, napththenic oil, paraffinic oil or a combination thereof. The ethylene/α-olefin interpolymers are random block copolymers comprising at least a hard block and at least a soft block. The resulting blends can be used to make flexible molded articles.
