    摘要: Disclosed herein is a multi-layer golf ball having a core, an inner cover layer comprising an ionomer and having Shore D hardness of about 65 or less, and an outer cover layer comprising an ionomer and having a Shore D hardness of at least 60. The outer cover layer is harder than the inner cover layer. The core preferably comprises a high molecular weight polybutadiene that exhibits an ultra high Mooney viscosity. The sum of the thickness of the inner cover layer and the thickness of the outer cover layer is greater than 0.090 inches. A method of making the golf ball also is disclosed.

    摘要: A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a cover comprising a thermoplastic polyurethane material and a dendritic polymer in a solution containing an isocyanate functionality reactive material. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing.

    摘要: The present invention is a method for forming a golf ball, the method comprising mixing an aqueous polyurethane dispersion with an azridine to form an aqueous polyurethane dispersion/aziridine mixture. Then, adding the aqueous polyurethane dispersion/aziridine mixture to a water tank, to form a PUD/aziridine solution and dipping a polybutadiene core in the PUD/aziridine solution. The PUD/aziridine solution comprises 0.4 percent aziridine, 4 percent aqueous polyurethane dispersion, and 95.6 percent de-ionized water, which forms a dipped polybutadiene core. The dipped polybutadiene core is then dried at room temperature.
