    Abstract: Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and acid copolymer ionomer. The cover composition also can contain hydroxyl-containing compounds. The golf ball having the thermoplastic polyurethane cover can be treated with an isocyanate compound. The golf ball also can be treated with a hydroxyl and/or silane-containing compound. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. The coating methods have many benefits and the finished balls have good physical properties.

    Abstract: Multi-layered golf balls having a core made of a foamed composition, preferably polyurethane foam, 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 an ionomer composition comprising an O/X-type acid copolymer, wherein O is α-olefin, and X is a C3-C8 α,β-ethylenically unsaturated carboxylic acid. The outer cover may be made from a non-foamed thermoset or thermoplastic material such as polyurethane. 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: Golf ball incorporating thermoplastic blend of (i) ionomer(s); (ii) different thermoplastic polymer(s) selected from thermoplastic polyurethane(s), thermoplastic urea(s), and/or thermoplastic urea-urethane hybrid(s); and (iii) acrylonitrile styrene acrylate(s) and/or acrylonitrile butadiene styrene(s) (“ASA and/or ABS”). Ionomer(s) present in amount of about 45 wt % or greater and ASA and/or ABS present in amount of from about 2 wt % to about 35 wt %. Thermoplastic polymer(s) may be present in amounts about 8 wt % to about 50 wt %; or about 25 wt % to about 45 wt %; or about 35 wt % to about 50 wt %. Ionomer amount may be greater than thermoplastic polymer amount. Thermoplastic polymer may be a polyurethane present in amount of greater than 20 wt % to about 40 wt %; while ASA and/or ABS is present in amount of from about 5 wt % to about 30 wt %. ASA and/or ABS sometimes present in amount of from about 15 wt % to about 35 wt %.
