Abstract
The invention relates to an oil extended ethylene-a-olefin-non-conjugated-diene copolymer composition consisting of i) 100 parts of at least one ethylene-a-olefin-non-conjugated-diene copolymer having —a weight average molecular weight (Mw) of at least 300,000 g/mol. —an intrinsic viscosity higher than 4, preferably higher than 4.2 measured in Xylene at 70° C. and —a polydispersity (Mw/Mn) smaller than 3, preferably smaller than 2.8, in particular smaller than 2.6; ii) 30 to 70 parts by weight per 100 parts by weight of the ethylene-a-olefin-non-conjugated-diene copolymer (i) of an extender oil and iii) up to 5 parts by weight per 100 by weight of the ethylene-a-olefin-non-conjugated-diene copolymer (i) of auxiliary agents, whereby the oil extended copolymer composition has a phase angle Ōof lower than 2.5.
