Abstract
Thermoplastic and thermoset compositions including hydroxyurethane linkages, golf ball components formed using such thermoplastic or thermoset compositions, and golf balls including such golf components.
Claims20
A golf ball, comprising:
- a core;
- and
- a cover, wherein the cover is formed from a composition comprising hydroxyurethane linkages and urethane linkages, and wherein the composition comprises a first reaction product of at least one cyclic carbonate and at least one amine-terminated component and a second reaction product of an isocyanate-containing component and an isocyanate-reactive component.
A golf ball, comprising:
- a core;
- and
- a cover, wherein the cover is formed from a composition comprising hydroxyurethane linkages and urea linkages, and wherein the composition comprises a first reaction product of at least one cyclic carbonate, at least one amine-terminated component, and an amine-terminated chain extender, and a second reaction product of an isocyanate-containing component and an isocyanate-reactive component.
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 comprising hydroxyurethane linkages from the reaction product of a cyclic carbonate, an amine-terminated component, and a chain extender;
- adding an isocyanate-containing component to the first reaction product to form a second reaction product comprising hydroxyurethane and urethane and/or urea linkages;
- and
- forming a cover disposed about the sub-assembly, the cover comprising the second reaction product.
