Abstract
A rubber composition containing (A) 100 parts by weight of an amorphous or low-crystalline ethylene-.alpha.-olefin copolymer rubber having an ethylene content of 70 to 90 mole %, a molecular weight distribution (Mw/Mn) of 3.0 or more and a Mooney viscosity ML.sub.1+4 (100.degree. C.) of 5 to 80; and (B) 1 to 120 parts by weight of a liquid ethylene-.alpha.-olefin random copolymer having an ethylene content of 40 to 90 mole % and an intrinsic viscosity [.eta.] of 0.01 to 0.4 dl/g as measured in decalin at 135.degree. C.
