Abstract
Thermoplastic and thermoset compositions for use in golf balls that are formed from bio-based materials and that include urethane linkages, golf ball components formed using such thermoplastic or thermoset compositions, and golf balls including such golf components.
Claims18
A golf ball, comprising:
- a core;
- and
- a cover, wherein the cover is formed from a composition comprising a reaction product of an isocyanate-reactive component and an isocyanate-containing component, wherein the isocyanate-reactive product comprises a precursor reaction product of at least one oxygen-containing heterocycle and carbon dioxide in the presence of a seed component, wherein the seed component comprises two or more primary or secondary hydroxyl and/or amine functional groups.
A golf ball, comprising:
- a core;
- and
- a cover, wherein the cover is formed from a composition comprising a second reaction product of a prepolymer and a chain extender, wherein the composition comprises urethane linkages, wherein the prepolymer comprises a first reaction product of an isocyanate-reactive component and an isocyanate-containing component, wherein the isocyanate-reactive product comprises two primary functional hydroxyl groups at each end of a polycarbonate backbone, and wherein the isocyanate-reactive product is a precursor reaction product of at least one oxygen-containing heterocycle and carbon dioxide in the presence of a seed component, wherein the seed component comprises two or more primary or secondary hydroxyl and/or amine functional groups.
A method of forming a golf ball, comprising the steps of:
- providing a golf ball sub-assembly comprising at least one core layer;
- forming a first reaction product from carbon dioxide and an oxygen-containing heterocycle, wherein the first reaction product comprises a carbonate backbone with primary hydroxyl groups at each end of the backbone;
- adding an isocyanate-containing component to the first reaction product to form a second reaction product comprising urethane linkages;
- and
- forming a cover disposed about the sub-assembly, the cover comprising the second reaction product.
