Patent ID: 7417106

Claim:
A golf ball comprising: a core, the core having a diameter; and at least one layer disposed about the core, the layer having a thickness, wherein the layer is formed from a polyurea composition, wherein the polyurea is formed by reacting a polyurea prepolymer with an amine curative, and wherein the polyurea prepolymer is formed by reacting a polyisocyanate with a sterically hindered polyamine having one of the following structures: where —(R 8 ) x NHR 2 and —(R 7 ) y CO— are ortho- or meta-substituents on the cyclic rings; A is the same or different moieties chosen from O, S, and NR; R is hydrogen or organic moieties having 1 to 20 carbon atoms; R 1 is a divalent or polyvalent organic moieties having at least one carbon or silicon atom; R 2 is hydrogen or organic moieties having 1 to 20 carbon atoms; R 3 to R 6 are independently chosen from hydrogen, halides, nitro, and organic moieties having 1 to 20 carbon atoms; R 7 is an organic moiety having at least one C, O, N, S, or Si atom; R 8 is a divalent organic moiety having one carbon atom connecting —NHR 2 to the cyclic ring; m is greater than 1; and x, y, and z are independently 0 or 1.
