Abstract:
An ethylene-&agr;-olefin-unconjugated polyene random copolymer rubber characterized by containing in a molecule hydrolyzable silyl groups represented by the following general formula (1): wherein R is a monovalent hydrocarbon group of 1 to 12 carbon atoms, X is a hydrolyzable group selected from the group consisting of hydride, halogen, alkoxy, acyloxy, ketoxymate, amide, acid amide, and aminoxy groups, and the letter â€œaâ€  is an integer of 0, 1 or 2, and obtained by subjecting an ethylene-&agr;-olefin-unconjugated polyene random copolymer rubber to hydrosilylation reaction in the presence of a catalyst in the form of a transition metal complex with a silicon compound of the following general formula (2):Hâ€”SiRaX3âˆ’aâ€ƒâ€ƒ(2) wherein R, X and Letter â€œaâ€  are as defined above, thereby adding the SiH group of said silicon compound to a double bond in said copolymer.
