ELASTOMER COMPOSITIONS AND PROCESSES FOR PRODUCING THE SAME

摘要

There is disclosed a moisture-curable elastomer composition obtained by dynamic heat treatment of a mixture comprising (a) an ethylene- alpha -olefin-unconjugated diene copolymer rubber, (b) a silicon-based crosslinking agent having two or more SiH groups within the molecule, (c) a hydrosilylation catalyst and (d) a hydrolyzable silane group-containing thermoplastic resin. Also disclosed is an elastomer composition resulting from molding of the above elastomer composition, followed by contacting with water, preferably in the presence of a silanol catalyst, to thereby cause crosslinking of the hydrolyzable silane group-containing thermoplastic resin. The elastomer composition of the present invention is excellent in rubber elasticity at high temperatures, low temperature impact resistance and oil resistance and have good moldability
