Claims
- 1. A golf ball comprising a cover and a molded single fatty acid core, said single fatty acid core comprising:
- an elastomer selected from high-cis polybutadiene and mixtures of high-cis polybutadiene with other elastomers;
- 25-37 phr based upon 100 phr elastomer of a homogeneous blend of 85-95% by weight zinc diacrylate and 5-15% by weight zinc palmeatate, formed from the reaction of
- palmitic acid,
- acrylic acid, and
- zinc oxide; and
- 1.0-5.0 parts by weight of a free radical initiator based upon 100 parts elastomer.
- 2. The golf ball of claim 1 wherein the core further comprises 3-20 phr by weight of zinc oxide.
- 3. The golf ball of claim 1 wherein the core further comprises 3-20 phr by weight of zinc oxide and one or more fillers.
- 4. The golf ball of claim 1 wherein the core comprises
- 1.0-3.0 parts by weight of a free radical initiator based upon 100 parts elastomer.
- 5. The golf ball of claim 4 wherein the core further comprises 3-20 phr by weight of zinc oxide.
- 6. The golf ball of claim 4 wherein the core further comprises 3-20 phr by weight of zinc oxide and one or more fillers.
- 7. The golf ball of claim 1 wherein the core further comprises ground core spew in the amount of 3 to 10% by weight of the core formulation.
- 8. An improved core composition for a golf ball, said composition comprising
- an elastomer selected from high-cis polybutadiene and mixtures of high-cis polybutadiene with other elastomers;
- 25-37 phr based upon 100 phr elastomer of a homogeneous blend of 85-95% by weight zinc diacrylate and 5-15% by weight zinc palmeatate, formed from the reaction of
- palmitic acid,
- acrylic acid, and
- zinc oxide; and
- 1. 0-5.0 parts by weight of a free radical initiator based upon 100 parts elastomer.
- 9. The core composition of claim 8 further comprising 3-20 phr by weight of zinc oxide.
- 10. The core composition of claim 8 further comprising 3-20 phr by weight of zinc oxide and one or more fillers.
- 11. The core composition of claim 8 wherein the core comprises:
- 1.0-3.0 parts by weight of a free radical initiator based upon 100 parts elastomer.
- 12. The core composition of claim 11 further comprising 3-20 phr by weight of zinc oxide.
- 13. The core composition of claim 11 further comprising 3-20 phr by weight of zinc oxide and one or more fillers.
- 14. The composition of claim 8 wherein the core further comprises ground core spew in the amount of 3 to 10% by weight of the composition.
- 15. A method for making an improved core for a high performance two piece golf ball comprising:
- (a) providing a base elastomer selected from high-cis polybutadiene and mixtures of high-cis polybutadiene with other elastomers;
- (b) providing 25-37 phr based upon 100 phr elastomer of a homogeneous blend of 85-95% by weight zinc diacrylate and 5-15% by weight zinc palmeatate, formed from the reaction of
- palmitic acid
- acrylic acid, and
- zinc oxide; and
- (c) blending the compositions of step (a) and (b) with 1.0 to 5.0 parts by weight of a free radical initiator based upon 100 parts elastomer;
- (d) molding the composition of step (c) to form a golf ball core.
- 16. The method of claim 15 further comprising blending 3-20 phr by weight of zinc oxide into the blend of step (c).
- 17. The method of claim 15 further comprising blending 3-20 phr by weight of zinc oxide and one or more fillers into the blend of step (c).
- 18. The method of claim 15 further comprising the step of adding 3-10% by weight ground core spew with particle size less than 30 mesh to the composition mixing in step (c) prior to the molding step.
