| 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 (eta), as measured in decalin at 135 degree C, is in the range of 0.1 to 8.0 dl/g, and (iv) the ratio g(eta*) of the intrinsic viscosity (phi) of the copolymer defined above to the intrinsic viscosity (eta) blank of a linear ethylene-prpoylene 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, (eta)/(eta)blank, is in the range of 0.2 to 0.9 or the ration g' of the intrinsic viscosity (eta) of said random copolymer defined above to the intrinsic viscosity (eta)blank' of a linear ethylene-propylene copolymer having and ethylene content of 70% by mol which is determined by measurement of gel permeationn chromatography (GPC) of ethylene-alpha-olefin-nonconjugated polyene random copolymer in orthodichlorobenzene at 140 degree C, (eta)/(eta)blank', is in the range 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. |
