Abstract
The present invention relates to the use of a fatty acid (meth)acrylic acid salt in a golf ball layer. The fatty acid (meth)acrylic acid salt may be added to one or more portions of a golf ball including a core, intermediate, or cover layer. For example, in one embodiment, the fatty acid (meth)acrylic acid salt may be blended with a polybutadiene rubber material. In another embodiment, the fatty acid (meth)acrylic acid salt of the present invention may be blended with an ionomer. In some embodiments, the fatty acid (meth)acrylic acid salt may be blended with a formulation including both a polybutadiene rubber component and an ionomer.
Claims19
A golf ball comprising a cover, a core, and an intermediate layer disposed between the cover and the core, wherein the core comprises:
- a blend of a polybutadiene rubber and a fatty acid (meth)acrylic acid salt, wherein the fatty acid (meth) acrylic acid salt comprises the reaction product of a fatty acid, a (meth)acrylic acid monomer, and M(OH)x or MxOy, where M is a metal cation and x and y independently range from about 1 to about 7, and wherein the fatty acid (meth)acrylic acid salt is present in the blend, in an amount of about 1 phr to about 70 phr.
A golf ball comprising a core and a cover disposed about the core, wherein the cover comprises:
- a blend of an ionomer resin and a fatty acid (meth)acrylic acid salt, wherein the fatty acid (meth)acrylic acid salt comprises the reaction product of a fatty acid, a (meth)acrylic acid monomer, and a M(OH)x or MxOy, where M is a metal cation and x and y independently range from about 1 to about 7, and wherein the fatty acid (meth)acrylic acid salt is present in the blend in an amount of about 1 weight percent to about 50 weight percent.
A golf ball comprising a core, an intermediate layer disposed about the core, and a cover disposed about the intermediate layer, wherein the intermediate layer comprises:
- a blend of a polybutadiene rubber in an amount of about 5 weight percent to about 90weight percent, an ionomer resin in an amount of about 5 weight percent to about 90 weight percent, and a fatty acid (meth)acrylic acid salt in an amount of about 1 weight percent to about 50 weight percent.
