    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 is preferably made from a foamed composition. In one embodiment, pre-expanded thermoplastic polyurethane foam beads containing a blowing agent are used to form the foam center and outer core. In another embodiment, pre-formed polyurethane foam particles are used in both core layers. 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.

    Abstract: Golf ball and method for making it, comprising a first layer that comprises a first polymeric composition and is surrounded by and adjacent to a second layer comprising a second polymeric composition different than the first polymeric composition; with one of these layers further comprising at least one silane-containing adhesion promoter such as organosilanes and/or organosiloxanes throughout in an amount of from about 0.1 wt. % to about 5.0 wt. % of the entire layer. Neither layer is surface treated with at least one silane-containing adhesion promoter. The second layer may be the layer comprising the silane-containing adhesion promoter throughout, surrounded by a third layer that comprises a third polymeric composition that differs from the second polymeric composition and does not incorporate any silane-containing adhesion promoter. Strong interlayer bonding is therefore created both between the second layer and the first layer and between the second layer and the third layer.
