Abstract
Abstract The invention provides an ethylene-α-olefin-unconjugated polyene random copolymer rubber having hydrolyzable silyl groups in the molecule, which is crosslinkable with air-borne moisture at room temperature and is not only useful for resin modification, but also applicable as elastic sealants and adhesives, and a method for preparing the same.

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.
