Low spin golf ball

摘要

The present invention is directed to a golf ball comprising a soft diene polymer core and a hard ionomer resin cover to produce a resulting molded golf ball having a reduced spin rate of not greater than 7643 revolutions per minute when struck with a No. 9 iron at a head speed of 105 feet per minute and a launch angle of 26 to 34 degrees rate. 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 without sacrificing durability, playability and resilience. The core has a Riehle compression of at least 0.075, and the cover has a Shore D hardness of at least 65.
