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 core comprising polybutadiene;
an inner mantle layer disposed over the center core;
an outer mantle layer disposed over the inner mantle layer;
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 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. The golf ball according to claim 1 wherein the center 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 center core;
an outer mantle layer disposed over the inner mantle layer;
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 at least one material selected from the group consisting of a farnesene, a poly(farnesene), and a farnesene copolymer.
4. A golf ball comprising:
a core comprising polybutadiene;
an inner mantle layer disposed over the center core;
an outer mantle layer disposed over the inner mantle layer;
a cover layer disposed over the outer mantle layer;
wherein at least one of the core, the inner mantle layer, the outer mantle layer or the cover layer comprises a blend material of at least one of a farnesene, a poly(farnesene), and a farnesene copolymer, and at least one of a partially-neutralized copolymeric ionomer, copolymeric ionomer, a partially-neutralized terpolymeric ionomer, and a terpolymeric ionomer.
