Abstract

PURPOSE: To provide a rubber composition consisting of a specific ethylene.α- olefin.-polyene copolymer rubber and a specific silane compound, giving a crosslinked product having high modulus and high creep resistance even at high temperature, and suitable as an electrical insulating material, etc.
CONSTITUTION: The objective rubber composition is prepared by the thermal reaction of (A) an ethylene.α-olefin.polyene copolymer rubber wherein the molar ratio of ethylene to (pref. 4W10C) α-olefin (e.g. 1-butene) is about 93/7W 87/13 (the polyene component is pref. 1,4-hexadiene and its content is pref. about 4W50 in terms of iodine value) and (B) a silane compound of formula RR'SiY2 (R is univalent olefinic unsaturated group; Y is hydrolyzable organic group; R' is univalent hydrocarbon group free from olefinic unsaturated groups, or Y) (pref. vinyltriethoxysilane). The weight ratio of A/B is pref. 100/(0.5W8).
