Abstract
An acrylic rubber composition comprising a halogen-containing acrylic rubber, a vulcanizing agent and at least one unsaturated compound selected from the group consisting of (1) .alpha.-olefins having at least 4 carbon atoms, (2) carboxylic acid vinyl esters, (3) alkyl vinyl ethers, (4) lower alkyl cyclohexenes or cyclohexenecarboxylic acid caprolactone esters and (5) unsaturated dicarboxylic acid diesters can give vulcanization products having an improved compression set without any substantial deterioration of normal state physical properties and resistance to heat ageing of the vulcanization products, where the unsaturated compound gives off no unpleaseant odor without any skin irritation when vulcanized and without lowering the mold releasability.
