Abstract

The present invention relates generally to golf balls containing a centipede polymer in one or more core layers, one or more cover layers, one or more intermediate layers.

Claims

1. A golf ball comprising one or more core layers and one or more cover layers, wherein at least one layer of the golf ball comprises a centipede polymer, and wherein the centipede polymer comprises a non-ionomeric poly(isoprene-g-styrene) centipede polymer.

2. The golf ball of claim 1, wherein the centipede polymer is present in one or more core layers.

3. The golf ball of claim 2, wherein the one or more core layers together have an outer diameter from about 1.50 inches to at least about 1.58 inches.

4. The golf ball of claim 2, wherein the golf ball comprises an inner core layer and an outer core layer, and wherein the centipede polymer is present in the outer core layer.

5. The golf ball of claim 1, wherein the golf ball additionally comprises an intermediate layer, and wherein the centipede polymer is present in an the intermediate layer.
