Abstract

The use of a low molecular weight farnesene, poly(farnesene), and farnesene copolymer in a golf ball is disclosed herein. In a core, low molecular weight farnesene, poly(farnesene) or farnesene copolymer is blended with 1,4 polybutadiene or a polyalkenamer. In a mantle layer, low molecular weight farnesene, poly(farnesene), and/or farnesene copolymer can be blended with non- or partially neutralized copolymeric or terpolymeric ionomer(s). In a cover, low molecular weight farnesene, poly(farnesene), and farnesene copolymer can be blended with highly neutralized ionomer.

Claims (13)

1 . A golf ball comprising:

a core comprising polybutadiene;

an inner mantle layer disposed over the core, the inner mantle comprising an ionomer material;

an outer mantle layer disposed over the inner mantle layer, the outer mantle comprising an ionomer material;

a cover layer disposed over the outer mantle layer;

wherein the cover layer comprises a blend material of at least one material selected from the group consisting of a farnesene, a poly(farnesene), and a farnesene copolymer, and a terpolymeric ionomer.

2 . The golf ball according to claim 1 wherein the core further comprises at least one of peptizers, accelerators, inhibitors, activators, colorants, foaming agents, and organic, inorganic or metallic fillers or fibers.

3 . A golf ball comprising:

a core comprising polybutadiene;

an inner mantle layer disposed over the core, the inner mantle comprising an ionomer material;

an outer mantle layer disposed over the inner mantle layer, the outer mantle comprising an ionomer material;

a cover layer disposed over the outer mantle layer;

wherein the cover layer comprises a blend material of a blend material of a highly neutralized ionomer and a farnesene copolymer.
