ABSTRACT:
It has now been discovered that the hydrogenation of unsaturated homo and copolymers can be effectively carried out in the absence of added gaseous hydrogen by contacting the unsaturated polymer with a hydrogen donor compound in the presence of a Group VIII metal catalyst, especially a supported palladium catalyst, for a time and at a temperature sufficient to bring about the hydrogenation of the unsaturated polymer.
