Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 69 words
An ethylene-α-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 "a" is an integer of 0, 1 or 2.
Claim 2
Dependent Claim 11 words
The copolymer rubber of claim 1 having fluidity at room temperature.
Claim 3
Dependent Claim 175 words
A method for preparing the ethylene-α-olefin-unconjugated polyene random copolymer rubber of claim 1 or 2, characterized by subjecting an ethylene-α-olefin-unconjugated polyene random copolymer rubber in which the unconjugated polyene is at least one terminal vinyl group-containing norbornene compound of the following general formula (I) or (II): wherein n is an integer of 0 to 10, R 1 is hydrogen or an alkyl group of 1 to 10 carbon atoms, and R 2 is hydrogen or an alkyl group of 1 to 5 carbon atoms, wherein R 3 is hydrogen or an alkyl group of 1 to 10 carbon atoms, to hydrosilylation reaction with a silicon compound of the following general formula (2): 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 "a" is an integer of 0, 1 or 2, thereby adding the SiH group of said silicon compound to a double bond in said copolymer.
