A composition for use in forming a multi-block copolymer, said copolymer containing therein two or more segments or blocks differing in chemical or physical properties, a polymerization process using the same, and the resulting polymers, wherein the composition comprises the admixture or reaction product resulting from combining: 1. An olefin interpolymer having a Mw/Mn from 1.7 to 3.5 {'br': None, 'i': y*>−', 'H, '0.1299(Δ)+62.81'}, 'a delta quantity (tallest DSC peak minus tallest CRYSTAF peak) greater than the quantity, y*, defined by the equationand a heat of fusion up to 130 J/gwherein the CRYSTAF peak is determined using at least 5 percent of the cumulative polymer, and if less than 5 percent of the polymer has an identifiable CRYSTAF peak, then the CRYSTAF temperature is 30° C., and ΔH is the numerical value of the heat of fusion in J/g.2. The olefin interpolymer of wherein the ethylene/α-olefin copolymer comprises greater than 50 mol % units derived from ethylene.3. The olefin interpolymer of wherein the ethylene/α-olefin copolymer comprises a comonomer selected from the group consisting of butene claim 2 , hexene claim 2 , and octene.4. The olefin interpolymer of wherein the ethylene/α-olefin copolymer has one and only one melting point.5. The olefin interpolymer of wherein the ethylene/α-olefin copolymer has a glass transition temperature claim 2 , Tg claim 2 , less than −25° C.6. The olefin interpolymer of comprising at least three metals.7. The olefin interpolymer of wherein at least one of the metals is hafnium.
