Abstract
Disclosed herein are polymer blends comprising at least one ethylene/α-olefin interpolymer and two different polyolefins which can be homopolymers. The ethylene/α-olefin interpolymers are block copolymers comprising at least a hard block and at least a soft block. In some embodiments, the ethylene/α-olefin interpolymer can function as a compatibilizer between the two polyolefins which may not be otherwise compatible. Methods of making the polymer blends and molded articles made from the polymer blends are also described.
