<p>A rubber composition which comprises (A) a rubber ingredient consisting of (a) a highly saturated nitrile copolymer rubber having an iodine value of 120 or lower, preferably a hydrogenated, unsaturated nitrile/conjugated diene copolymer, and (b) a polyacrylic ester polymer rubber, preferably a copolymer rubber comprising at least 80 mol% of alkyl or alkoxyalkyl acrylate units in an (a) to (b) weight ratio of 40/60 to 90/10 and (B) an ethylene/α-olefin copolymer, and in which the (A) to (B) weight ratio is 30/70 to 70/30. This rubber composition is useful as a wire coating material for forming a protective coating layer on electric wires.</p> |
