<P>PROBLEM TO BE SOLVED: To provide a rubber composition, a method for manufacturing the rubber composition, and a rubber component, which show high damping performance and impact absorption performance even in a high temperature region. <P>SOLUTION: The rubber composition contains 10 parts by mass or more of a coumarone resin based on 100 parts by mass of a polymer with rubber elasticity. It is desirable that a contained amount of the coumarone resin is 20 parts by mass or more. It is desirable that the polymer with rubber elasticity is natural rubber, modified natural rubber, or functionalizing natural rubber, and the epoxidized natural rubber is particularly desirable. The rubber component is obtained by using the rubber composition which contains 10 parts by mass or more of the coumarone resin based on 100 parts by mass of the polymer with rubber elasticity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
