<p>Provided is an ethylene-alpha-olefin-non-conjugated polyene copolymer which contains an ethylene unit, an alpha-olefin unit and a non-conjugated polyene unit and satisfies the following conditions (A), (B), (C), (D) and (E). (A) The limiting viscosity [eta] is 0.5-1.8 dl/g. (B) When the total of the content of ethylene units and the content of alpha-olefin units is taken as 100% by mole, the content of ethylene units is 50-90% by mole and the content of alpha-olefin units is 50-10% by mole. (C) The iodine number is 1-50. (D) The ratio of the tandelta at 100°C and 2 cpm to the tandelta at 100°C and 1,000 cpm is 1.0-1.7. (E) The ratio of the Z-average molecular weight to the number average molecular weight is 15-25, and the ratio of the weight average molecular weight to the number average molecular weight is 3-5.</p> |
