(57) Abstract: An ethylene / α-olefin / non-conjugated polyene random copolymer of the present invention has a specific composition, an iodine value, an intrinsic viscosity, an intensity ratio D (Tαβ / Tαα), a B value and It has a glass transition temperature Tg. [Effect] The ethylene / α-olefin / non-conjugated polyene random copolymer of the present invention has a narrow composition distribution, excellent mechanical strength, excellent low-temperature flexibility and heat aging resistance, Excellent weather resistance and ozone resistance. A vulcanizable rubber composition containing such an ethylene / α-olefin / non-conjugated polyene random copolymer is excellent in mechanical strength, weather resistance, ozone resistance, workability, and the like, and has cold resistance (low temperature). Flexibility) and heat resistance. The rubber composition according to the present invention can form a vulcanized rubber molded article or a vulcanized rubber foam particularly excellent in such properties. |
