| abstract | The present invention is a method for producing an ethylene /? - olefin / nonconjugated polyene random copolymer, which is an ethylene random copolymer satisfying the following conditions (1) to (5) simultaneously.n n n (1) the molar ratio of ethylene (a) to? -Olefin (b) having 3 to 20 carbon atoms is from 40:60 to 95: 5;n n n (2) the non-conjugated polyene (c) has a norbornene skeleton;n n n (3) Effective net cancellation density ( ) Is at least 1.5 x 10 20 / cm 3 after pressurized crosslinking of the copolymer using dicumyl peroxide;n n n (4) shear rate when the shear force shown in the belt flow curve at 100 ° C is 0.4 x 10 6 dyne / cm 2 1) Shear rate when the shear force is 2.4x10 6 dyne / ㎠ 2), that is, 2/ 1 has a relationship represented by the following general formula [I];n n n n n n n n (5) Intrinsic viscosity measured in decalin at 135 ° C [ ] Is 0.5 to 10 dl / g.n n n The copolymer is excellent in crosslinkability and can be crosslinked with a small amount of peroxide or the like. The crosslinked rubber composition prepared using such a copolymer is excellent in resistance to aging, mechanical stiffness, weather resistance and ozone resistance. |
