Abstract
There is provided a composition comprising a higher a-olefin copolymer (1) obtained by copolymerization in the presence of a specific olefin polymerization catalyst of a specific higher .alpha.-olefin, a specific .alpha., .omega.-diene of the formula (I) and a specific non-conjugated diene of the formula (II), and a rubber (2) selected from the group consisting of a diene rubber, an ethylene/a-olefin copolymer, a nitrile rubber and a hydrogenated nitrile rubber. The composition is excellent in workability strength characteristics, weatherability, ozone resistance and dynamic fatigue resistance, as well as excellent in adhesive properties to fiber and in vibration-insulating properties and damping properties.
