<p>Crosslinkable rubber compositions which can be crosslinked at room temperature, exhibit gelation times of 30 days or below at room temperature, and can give through room-temperature crosslinking crosslinked rubber sheets having tensile elongations of 20 % or above and not suffering from cracking even after the treatment at 40?C in an atmosphere of an ozone concentration of 50 pphm for 96 hours. Specifically, a composition comprising an ethylene/a-olefin/nonconjugated polyene random copolymer rubber wherein the nonconjugated polyene is a specified norbornene having a terminal vinyl group, an SiH compound having two or more SiH groups, and, if necessary, a platinum catalyst, a reaction inhibitor and/or a silane coupling agent; and sealing compounds, potting materials, coating materials and adhesives, containing the composition.</p> |
