Abstract
The present invention is directed to a golf ball comprising a soft core and a hard cover to produce a resulting molded golf ball having a reduced spin 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.
Claims16
A golf ball comprising:
- a molded core comprising a diene polymer, said core having a Riehle compression of at least 80;
- and
- a cover having a Shore D hardness of at least 65, wherein the cover is comprised of at least one high acid ionomer resin comprising a copolymer of greater than 16% by weight of an alpha, beta-unsaturated carboxylic acid, and an alpha-olefin of which about 10% to about 90% of the carboxyl groups of the copolymer are neutralized with a metal cation.
A low spin, two-piece golf ball comprising:
- a core comprising a diene polymer and having a Riehle compression of at least 75;
- a cover having a Shore D hardness of at least 68, wherein the cover is comprised of at least one high acid ionomer resin comprising a copolymer of greater than 16% by weight of an alpha, beta-unsaturated carboxylic acid, and an alpha-olefin of which about 10% to about 90% of the carboxyl groups are neutralized with a metal cation.
A molded two piece golf ball comprising a core comprising diene polymer and a cover comprising a high acid ionomer resin, wherein the core has a Riehle compression of 80 to 115, and wherein the cover has a Shore D hardness of 68 or more, further wherein the cover comprises a copolymer of greater than 16% by weight of an alpha, beta-unsaturated carboxylic acid, and an alpha-olefin of which about 10% to about 90% of the carboxyl groups are neutralized with a metal cation, and wherein the cover thickness is greater than about 0.080 inches.
