Abstract
A golf ball with a cover or mantle layer that comprises a polyurethane and ionomer hybrid made by compounding or dry blending acid functional polyurethane and an ionomer is disclosed herein. The golf ball comprises a core (single core or dual core), a mantle layer (single layer or dual layer) and a cover layer.
Claims9
A golf ball comprising:
- a center core;
- a mantle layer;
- and
- a cover layer disposed over the mantle layer;
- wherein at least one of the cover layer or the mantle layer comprises a maleic anhydride functional polymer and an acid functional polyurethane and ionomer hybrid material made by compounding or dry blending an acid functional polyurethane and an ionomer, wherein the acid functional polyurethane and ionomer hybrid material is formed by reacting an isocyanate functional polymer with molecules that have both hydroxyl and acid functionalities;
- wherein the acid functional polyurethane and ionomer hybrid material is neutralized with titanium dioxide.

A golf ball comprising:
- a dual core comprising an inner core and an outer disposed over the inner core;
- a mantle layer disposed over the inner core;
- and
- a cover layer disposed over the mantle layer;
- wherein at least one of the cover layer or the mantle layer comprises a maleic anhydride functional polymer and an acid functional polyurethane and ionomer hybrid material made by compounding or dry blending an acid functional polyurethane and an ionomer, wherein the acid functional polyurethane and ionomer hybrid material is formed by reacting an isocyanate functional polymer with molecules that have both hydroxyl and acid functionalities;
- wherein the acid functional polyurethane and ionomer hybrid material is neutralized with titanium dioxide.
