Use of farnesene, polyfarnesene and farnesene copolymer for golf balls
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.
1. A golf ball comprising:
a center core comprising polybutadiene;
an outer core disposed over the center core;
a mantle layer disposed over the outer core;
a cover layer disposed over the 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 at least one material selected from the group consisting of a partially-neutralized copolymeric ionomer, copolymeric ionomer, a partially-neutralized terpolymeric ionomer, and a terpolymeric ionomer.
2. A golf ball comprising:
a center core comprising polybutadiene;
an outer core disposed over the center core;
a mantle layer disposed over the outer core;
a cover layer disposed over the mantle layer;
wherein the cover layer comprises a blend material of a blend material of a highly neutralized ionomer and at least one material selected from the group consisting of a farnesene, a poly(farnesene), and a farnesene copolymer.
