Abstract
A composite comprised of a nitrile group-containing highly saturated copolymer rubber and a fibrous material, which copolymer rubber is a product obtained by hydrogenating the conjugated diene portion of an unsaturated nitrile-conjugated diene copolymer. The highly saturated copolymer rubber has an alkylthio group having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and having a sulfur atom which is directly bound to at least one of the tertiary carbon atoms; and the copolymer rubber further has a Mooney viscosity of 15 to 200 and an iodine value not larger than 80. This composite is useful for a belt.
