Abstract: The present invention provides methods for producing golf balls having polyurethane covers and the resultant balls. Multi-piece golf balls having an inner core and outer cover with one or more intermediate layers disposed between the core and cover can be formed. The methods involve producing hydroxyl-terminated adducts and isocyanate-terminated prepolymers. Thermoset and thermoplastic polyurethane compositions can be prepared. The resulting polyurethane compositions and golf ball covers have high thermal stability and good wear-resistance and durability.
