    摘要: Disclosed is an ethylene-α-olefin-nonconjugated polyene random copolymer having such properties that (i) the copolymer contains units derived from ethylene (a) and units derived from the α-olefin of 3 or more carbon atoms (b) in a molar ratio of 40/60 to 64/36 [(a)/(b)], (ii) the iodine value is 1 to 50, (iii) the intrinsic viscosity (η) is more than 0.3 dl/g and less than 5.0 10 dl/g, (iv) the intensity ratio D of Tαβ to Tαα in the 13 C-NMR spectrum, Tαβ/Tαα is not more than 0.5, (v) the B value is 1.00 to 1.50 and (vi) the glass transition temperature Tg is not higher than -50°C. Also disclosed is a vulcanizable rubber composition containing the random copolymer. A process of preparing this copolymer by using a metallocene catalyst containing a specified metallocene compound is also disclosed. The ethylene-α-olefin-nonconjugated polyene random copolymer and the rubber composition are excellent in mechanical strength, weathering resistance, ozone resistance, processability, low temperature flexibility and heat resistance.
