Zusammenfassung:	PROBLEM TO BE SOLVED: To provide ethylene/α-olefin interpolymers allowing manufacture of various articles and components such as wire, electrical insulators, and automotive components and tires.SOLUTION: Interpolymers prepared from ethylene/α-olefin and ethylene/α-olefin/diene monomers at an elevated temperature in an atmosphere that has little or no hydrogen using a constrained geometry complex catalyst and an activating cocatalyst have shear-thinning properties and are applicable to various articles or components. The α-olefin is a Cα-olefin. The weight ratio of ethylene to the α-olefin is within the range from 90:10 to 10:90. The interpolymer has a diene monomer content within the range of 0-25 wt.% based on the interpolymer weight. The interpolymer has a Mooney viscosity Lat 125°C within the range from 0.5 to 200.
