摘要： The present invention is directed to a golf ball comprising a core and a cover, wherein the cover comprises a blend of two or more high acid ionomer resins. Each high acid ionomer resin utilized in the blend of the cover composition comprises generally of greater than 16% by weight acid, preferably from about 17 to about 25% by weight acid and more preferably from about 18.5% to about 21.5% by weight acid. The acid groups of the high acid ionomers utilized in the cover compositions of the invention are partially (i.e. generally 10-75 percent, preferably 30-70 percent) neutralized by metal ions such as by sodium, zinc and magnesium ions. When the blend of two or more high acid ionomer resins is utilized to manufacture a golf ball, the golf ball produced thereby, exhibits properties of improved distance without sacrificing characteristics such as playability and/or durability when compared to low acid ionomer and/or low acid/high acid ionomer blends. In addition, the present invention is also directed to a golf ball comprising a soft core and a hard cover comprising a blend of high acid ionomer resins to produce a resulting molded golf ball having a reduced spin rate. The low spin golf ball of the present invention has an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.

摘要： The present invention is directed to improved molded golf ball core constructions and methods for improving the molded golf ball core construction. The molded golf ball comprises a molded spherical core having a soft skin integral therewith, and a cover molded over the core. The soft skin is formed by controlling exothermic molding temperatures. A slug is placed in a mold cavity which is then closed. A steam set point is set, and steam is applied for a 25-30 minute period such that a maximum mold temperature exceeds the steam set point. In the alternative, the core surface may be softened by first immersing a slug in water prior to subjecting the slug to conventional molding conditions.

摘要： The present invention is directed to a golf ball comprising a soft core and a hard cover to produce a resulting golf ball having a reduced spin rate. In this regard, a core is provided and metal particles, or other heavy weight filler materials, are included in the cover compositions. This results in a golf ball exhibiting enhanced perimeter weighting. Preferably, the particles are included in a relatively thick inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. In another preferred version, one or more patterns of weighting material are incorporated in the ball, and most preferably along the outer periphery of the ball so that the pattern is visible along the ball's exterior. The size and weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. It has been found that the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. The golf ball of the present invention may also utilize an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.

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 polypropylene powder resins which have the effect of increasing the hardness of the resulting molded cores without increasing the weight upon curing, thereby allowing for a reduction in the amount of crosslinking agents utilized and increasing the amount of fillers incorporated therein. The addition of the polypropylene powder resins to the core compositions lowers the cost of the molded core, while maintaining the proper weight and compression. The present invention is also directed to golf balls produced utilizing the improved core compositions. Furthermore, the invention is directed to a method for reducing the amount of crosslinking agents utilized to formulate a core composition through the incorporation of polypropylene powder resins. In addition, a method for decreasing the amount of crosslinking agents and increasing the amount of mineral fillers included in a core composition through the incorporation of polypropylene powder resins is also disclosed.

摘要： Disclosed herein is a golf ball having a non-ionomeric cover and method for making the same. The golf ball has been treated with crosslink-inducing irradiation at levels of at least 2 megarads up to 15 megarads. The non-ionomeric resin cover is made from material selected from the group consisting of non-ionomeric acid copolymers and terpolymers, polyamides, styrene block copolymers, polyamide block copolymers and syndiotactic resins. The golf ball cover is relatively soft, having a Shore D hardness that is no more than 10% greater than a cover having an identical composition but not radiation crosslinked. The cover is superior in cut resistance and scuff resistance to a conventional cover of substantially identical composition that is not covalently crosslinked. The golf ball cover of the invention is particularly useful for improving the durability of golf balls to be struck with sharp-grooved clubs.
