Golf balls comprising thermoplastic, thermoset, castable, or millable materials are presently disclosed. The materials have a rebound height percentage of greater than 60% and are formed from compositions comprising at least one resilient polyamine polydiene and/or polyol polydiene having a number average molecular weight of 1,000-20,000 and an amine or hydroxyl functionality of 1.6-10. The materials also have a 1,4-addition of 30-70% and/or a 1,2-addition of at least 40%. These materials can be used in any one or more portions of the golf balls, such as inner center, core, inner core layer, intermediate core layer, outer core layer, intermediate layer, cover, inner cover layer, intermediate cover layer, and/or outer cover layer.
