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.

Anti-blocking polymer compositions comprise at least one ethylene/α-olefin interpolymer and at least one anti-blocking agent comprising an amide. The ethylene/α-olefin interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. The anti-blocking agent can be erucamide or other amides. The anti-blocking polymer composition has a pellet blocking strength of equal to or less than 100 lbs/ft
2
(4800 Pa). When the anti-blocking polymer composition is made into a film, the film has a blocking force of less than about 100 grams, measured according to ASTM method D-3354.
