摘要:
The present invention is directed to a golf ball comprising a dual core component, an inner cover layer and an outer cover layer. The dual core comprises an interior spherical center component formed from a thermoset material, a thermoplastic material, or combinations thereof. The dual core also comprises a core layer disposed about the center component, formed from a thermoset material, a thermoplastic material, or combinations thereof. The one or more polyurethane layers are preferably formed via a reaction injection molding (RIM) technique. The inner cover layer is relatively soft and preferably comprises an ionomer or ionomer blend. The outer cover layer is relatively hard and comprises a hard polyurethane. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.

A golf ball is described that includes a spherical core, an inner cover or mantle layer, and an outer cover layer. A wide array of ionomeric materials are noted for use in the various cover layers. The mantle and the outer cover layers exhibit different Shore D hardness values and at least one of the layers includes a heavy weight filler material to enhance the interior perimeter weight of the ball. In several particular versions of the golf balls, the filler material is present in an amount of at least 10% by weight based upon the weight of the layer or layers within which the filler material is incorporated.

The present invention is directed to an improved multi-layer golf ball comprising a core, an inner cover layer and an outer cover layer. The inner cover layer is comprised of a high acid ionomer or ionomer blend which may or may not include a filler such as zinc-stearate. The outer cover layer is comprised of a soft, very low modulus ionomer or ionomer blend, or a non-ionomeric thermoplastic elastomer such as polyurethane, polyester or polyesteramide. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.

A game ball comprising an ionomeric cover which includes a combination of ionomeric crosslinks and radiation induced covalent crosslinks. The game ball cover may include non-ionomeric materials. The game ball cover is superior in at least one of cut resistance and scuff resistance to a conventional cover that does not have the covalent crosslinks but is otherwise substantially identical in composition. The game ball cover of the invention is particularly useful for improving the durability of golf balls to be struck with sharp-grooved clubs.

The present invention is directed to the use of gel material in a golf ball. In one aspect of the invention discrete gel particles form an integral structural and functional role in the hard-cover, mantle or core elements of a golf ball to provide an additional ways of varying the playability properties of a golf ball. In one embodiment the invention is directed to a golf ball comprising a mantle dispersed with discrete voids filled with gel to provide a heterogeneous mixture of at least one gel material and at least one non-gel material. In another embodiment of the invention 10 parts of ground down silica gel material, 50 parts Iotek® 1002, 50 parts Iotek® 1003, and 0.025 parts UM Blue to provide a composite mantle. In this embodiment the degree of measured compression (and good guide to deformability and initial spin rate when struck by a golf club) is increased with a commitment decrease in Shore C/D hardness. In another aspect of the invention discrete elastomeric particles form an integral structural and functional role in the hard-cover, mantle or core elements of a golf ball.

Disclosed herein is a multi-layer golf ball having a soft outer cover. The golf ball has an inner cover layer with a Shore D hardness of 60 or more, and an outer cover with a Shore D hardness of 55 or less, and more preferably 50 or less. In a particularly preferred form of the invention, the outer cover comprises at least 75% of a soft copolymer formed from a polyolefin, an unsaturated carboxylic acid, and a monomer of the acrylate ester class. The golf ball of the invention has exceptionally soft feel and high spin rates on short shots of 80 yards or less and, particularly, 40 yards or less, while maintaining good distance and average spin on full shots.

摘要:
The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polybutadiene compositions are composed of one or more certain types of polybutadiene, which has the effect of increasing the resiliency of the resulting molded cores and greatly facilitates processing of the compositions and forming the cores. Also disclosed are improved golf ball cores, and balls utilizing such cores, formed from particular ultra high Mooney viscosity polybutadiene. In another aspect, golf balls having particular cover compositions are disclosed. Such cover compositions include at least one sodium ionomer and at least one zinc ionomer. Also disclosed are golf balls having a mechanical impedance with a primary minimum value in a frequency range of 3100 Hz or less after the ball has been maintained at 21.1° C., 1 atm. and about 50% relative humidity for at least 15 hours. The balls of the invention have good distance while providing a soft sound and feel.
