titleOfInvention | Ethylene-.alpha.-olefin-nonconjugated polyene random copolymer, rubber composition, and process for preparing the random copolymer |
abstract | Disclosed is an ethylene-.alpha.-olefin-nonconjugated polyene random copolymer which is a random copolymer of (a) ethylene, (2) an .alpha.-olefin of 3 or more carbon atoms and (c) a nonconjugated polyene containing, in one molecule, one carbon-to-carbon double bond polymerizable by a metallocene catalyst among carbon-to-carbon double bonds, and has such properties that (i) the copolymer contains (a) units derived from ethylene and (b) units derived from the .alpha.-olefin of 3 or more carbon atoms in a molar ratio of 40/60 to 95/5 ((a)/(b)), (ii) the iodine value is in the range of 1 to 50, (iii) the intrinsic viscosity (?), as measured in decalin at 135 °C, is in the range of 0.1 to 8.0 dl/g, and (iv) the ratio g?* of the intrinsic viscosity (?) of the copolymer defined above to the intrinsic viscosity (?)blank of a linear ethylene-propylene copolymer having the same weight-average molecular weight (measured by light scattering method) as the ethylene-.alpha.-olefin-nonconjugated polyene random copolymer and having an ethylene content of 70 % by mol, (?)/(?)blank, is in the range of 0.2 to 0.9 or the ratio g' of the intrinsic viscosity (?) of said random copolymer defined above to the intrinsic viscosity (?)blank' of a linear ethylene-propylene copolymer having and ethylene content of 70 % by mol which is determined by measurement of gel permeation chromatography (GPC) of ethylene-.alpha.-olefin-nonconjugated polyene random copolymer in orthodichlorobenzene at 140 °C, (?)/(?) blank', is in the reange of 0.2 to 0.9. Also disclosed are a process for preparing the random copolymer and a vulcanizable rubber composition containing the random copolymer. The ethylene-.alpha.-olefin-nonconjugated polyene random copolymer and the rubber composition are excellent in weathering resistance, ozone resistance, mechanical strength and processability. |
