Abstract
The present invention relates to fiber-reinforced belts, such as timing belts or conveyor belts, which are manufactured from a hydrogenated nitrile rubber having oxazoline functionality. Thus, the hydrogenated nitrile rubber contains less than 10 mole percent carbon-carbon double bond unsaturation and a functional group which may be identified using infrared spectroscopy by a characteristic peak between 1552 cm.sup.-1 and 1668 cm.sup.-1. The present belts are further characterized by having excellent adhesion between the fiber reinforcement and the oxazoline functionalized hydrogenated nitrile rubber.
