Abstract
Golf balls exhibiting an improved coefficient of restitution are obtained by including zinc palmeatate in the core formulation.
Claims18
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.
