    Abstract: Methods for making golf balls having a cover made from a polyurea composition are provided. The golf balls include a rubber core and intermediate layer made from an olefin-based ionomer composition. The methods for making the polyurea composition involve preparing an amine-terminated first polymer by reacting isocyanate compound A with a stoichiometric excess of polyamine. The first prepolymer is reacted with a stoichiometric excess of isocyanate compound B to form an isocyanate-terminated second prepolymer. The second prepolymer is then reacted with a chain extender.

    Abstract: Multi-layered, golf balls having a core made of a particle-based polyurethane foam composition are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The surrounding outer core layer may be made from a non-foamed thermoset material such as polybutadiene rubber. In one embodiment, pre-expanded thermoplastic polyurethane foam beads containing a blowing agent are used to form the foam center. In another embodiment, pre-formed polyurethane foam particles are used. The foam cores have good resiliency, thermal stability, and durability over a wide temperature range. The ball further includes a cover that may be multi-layered.
