摘要： The present invention is directed to improved polybutadiene compositions suitable for use in molded golf ball core construction. The improved polyubutadiene 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 utilised 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： The present invention is directed to improved golf ball compositions in which the balls have low spin and excellent distance. The balls contain tungsten or another high density filler in a solid, central core in order to enhance coefficient of restitution, and have very high quantities of whitening agent in the outer cover layer to increase the moment of inertia and thus reduce spin. This results in a golf ball exhibiting enhanced distance while maintaining good durability. In a preferred version of the present invention, a golf ball is provided that comprises a core and a dimpled cover disposed about the core. The core includes a rubber and 0.1 to 40 parts by weight of a filler material having a specific gravity of at least 7. The cover includes a resin and at least 2.5 parts by weight of a particular whitening agent.

摘要： Disclosed herein is a game ball and method for making the same. The game ball has a non-ionomeric cover which has been crosslinked by incorporating a dialkyl peroxide in the polymer mix prior to molding. The game ball cover is superior in at least one of cut resistance and scuff resistance to a conventional cover that does not have 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 peroxide may be omitted and the cover crosslinked using post formation irradiation.
