    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.

    Abstract: Multi-layered golf balls having a core made of a foamed polyurethane composition are provided. The ball includes a dual-layered core having a foam inner core (center) and surrounding outer core layer. The outer core layer may be made from a non-foamed thermoset material such as polybutadiene rubber. The ball further includes an inner cover, preferably made from a thermoplastic ionomer. The outer cover may be made from a non-foamed thermoset or thermoplastic material such as polyurethane. The core and inner cover layers preferably have different densities so the Moment of Inertia of the ball is adjusted. Preferably, the specific gravity of the inner cover is greater than the specific gravity of the outer core, which is greater than the specific gravity of the inner core. The finished ball has good distance and low-spin properties.

    Abstract translation: 提供具有由发泡聚氨酯组合物制成的芯的多层高尔夫球。 球包括具有泡沫内芯（中心）并且围绕外芯层的双层芯。 外芯层可以由非发泡的热固性材料例如聚丁二烯橡胶制成。 球还包括优选由热塑性离聚物制成的内盖。 外盖可以由非发泡的热固性材料或热塑性材料如聚氨酯制成。 芯层和内覆盖层优选具有不同的密度，从而调整球的惯性矩。 优选地，内盖的比重大于外芯的比重，其大于内芯的比重。 成品球具有良好的距离和低旋转性能。
