Nitrile is a synthetic rubber. It has good resistance to chemicals and can withstand a wide range of temperatures. It is less elastic than latex, though, so nitrile gloves are not as close fitting as their latex couterparts and do not offer the same tactile sensitivity. This means that they are not suitable for surgery. They are also considerably more expensive.
