Polymer blends from interpolymer of ethylene/alpha-olefin with improved compatibility

摘要

Disclosed herein are polymer blends comprising at least one ethylene/a-olefm interpolymer and two different polyolefins which can be homopolymers. The ethylene/a- olefm interpolymers are block copolymers comprising at least a hard block and at least a soft block. In some embodiments, the ethylene/a-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.
