PROBLEM TO BE SOLVED: To provide block copolymers that have low crystallinity hard block based on ethylene and α-olefin.SOLUTION: An ethylene/α-olefin interpolymer has a hard segment and a soft segment, wherein (a) the interpolymer has a Mw/Mn from about 1.7 to about 3.5; and (b) it has an ethylene content in the hard segment in the range of from 60 to 95 wt % based on total monomer content in hard segment. The soft segment has a larger amount of comonomer than the hard segment. The hard segment is low in crystallinity. |
