Some did, specifically the Golden Horde in Russia [under Berke Quan, Batu's brother and successor] and, eventually, the Il-Quanate of Persia [Hulegu's uluis].

The Chagatids stayed largely pagan, as did many of the Mongols of Central Asia. And there was always a strong minority of Nestorian Christians.
