Polymer blends comprise at least one ethylene/&#x3b1;-olefin interpolymer and one or more oil. The oil can be an aromatic oil, napththenic oil, paraffinic oil or a combination thereof. The ethylene/&#x3b1;-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.

Oil based blends of interpolymers of ethylene/&#x3b1;-olefins

Polymer blends comprises 1) at least one ethylene/&#x3b1;-olefin interpolymer and 2) at least one polyolefin, or at least one styrenic block copolymer, or a combination thereof. Such polyolefins include, but are not limited to, high melt strength high density polyethylene and high melt strength polypropylene. The ethylene/&#x3b1;-olefin interpolymers are random block copolymers comprising at least a hard block and at least a soft block. The polyolefins can be homopolymers or interpolymers. The resulting polymer blends can be used to make flexible molded articles.
