Rubber composition |
摘要 |
<p>A rubber composition excellent in shape-retainability also in processibility, compression set and the like, which comprises a single ethylene- alpha -olefin-non-conjugated diene copolymer which has (1) a Mooney viscosity (ML1+4, 100 DEG C) of 80 to 200, (2) a weight average molecular weight/number average molecular weight ratio of 6 or more as measured by a gel permeation chromatography (GPC), and (3) a stress-retention of 0.2 or more after 100 seconds at 80 DEG C in a compression type stress-relaxation test.</p> |
