The 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 (i.e., the spin rate of the ball not being greater than 7541 r.p.m., preferably not greater than 7,500 r.p.m., when struck with a No. 9 iron at a head speed of 105 ft/sec. and a launch angle of 26 to 34 degrees) without sacrificing durability, playability and resilience.

摘要： A golf ball is provided having a controlled weight distribution about a designated spin axis. The golf ball includes a core defining one or more high density regions interiorly disposed along a common plane and centered about the horizontal spin axis of the ball. As a result of the controlled weight distribution, the resulting ball significantly reduces hooks and slices. A method of manufacturing and/or utilizing the present golf ball is also provided.

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.
