A multilayer golf ball with at least one layer made from an expandable polymeric composition is disclosed. In accordance to one aspect of the invention, the expandable polymeric composition comprises a film-forming binder polymer latex, a dispersing agent, a plurality of polyspheres encapsulating expandable volatile substance, and at least one additive. The additive can be a defoaming agent, a solvent, a thickener, a plasticizer, or any combination thereof. Another expandable polymeric composition comprises a curable silicone composition comprising a liquid diorganopolysiloxane, a liquid organosilicon compound, a condensation catalyst and a blowing agent. Another the expandable polymeric composition comprises an aqueous acrylic based latex emulsion and an unencapsulated blowing agent.
A multilayer golf ball comprising a core, an intermediate layer, and a cover, wherein the intermediate layer comprises an expandable polymeric composition, wherein the expandable polymeric composition expands from 5% to 200% of its pre-expand thickness when the expandable polymeric composition is exposed to a triggering environmental factor.
