To provide a rubber composition showing a sufficient heat resistance and durability and an excellent damping performance, a rubber molded product and their preparation processes.
The rubber composition contains (A) an ethylene/α-olefin copolymer rubber and (B) a crosslinked product obtained by adding (B-2) 0.05-5 pts.mass metal compound to (B-1) 100 pts.mass functional group-containing (co)polymer to crosslink the (B-1) functional group-containing (co)polymer by a metal component in the metal compound. Here, the contents of (A) the ethylene/α-olefin copolymer rubber and (B-1) the functional group-containing (co)polymer are 50-99 pts.mass and 1-50 pts.mass, respectively, based on 100 pts.mass total of (A) the ethylene/α-olefin copolymer rubber and (B-1) the functional group-containing (co)polymer.
