Abstract
A golf ball comprising a core, an intermediate layer, and a cover layer; wherein the intermediate layer is formed of a polymer blend comprising an ionomer having at least about 16% acid groups and a grafted-metallocene polymer; and the cover layer comprises a castable reactive liquid material. Optionally, a non-ionomer may be blended with the polymer blend or, in an alternative, the high acid ionomer may be blended solely with the non-ionomer.
Claims51
A golf ball comprising a core, an intermediate layer, and a cover layer;
- wherein the intermediate layer is formed of a polymer blend comprising an ionomer having at least about 16 percent acid groups and a grafted-metallocene polymer;
- and the cover layer comprises a castable reactive liquid material.
A golf ball comprising a core, an intermediate layer, and a cover layer, wherein the intermediate layer is formed of a polymer blend comprising an ionomer having at least about 16 percent acid groups, a non-ionomer, and a grafted-metallocene polymer, and the cover layer comprises a castable urethane.
A golf ball comprising a core, an intermediate layer, and a cover layer;
- wherein the intermediate layer is formed of a polymer blend comprising at least about 80 weight percent of an ionomer having at least about 16 percent acid groups, a non-ionomer, and a grafted-metallocene polymer;
- and the cover layer comprises a castable urethane.
