Patent ID: 6989431

Claim:
A golf ball comprising a core and a cover, wherein the core or the cover comprises a thermoplastic or thermoset composition comprising a polyurea prepolymer formed from: a reactant A comprising an isocyanate; and a reactant B comprising a polyamine having a polydispersity of 3 or less, the polyamine being a polyether polyamine comprising a repeating branched oxyalkylene monomer unit where Y 1 is a hydrocarbon; Y 2 , Y 3 , and Y 4 are independently hydrogen or hydrocarbons; a, b, and x are independent whole numbers of 0 to about 10; and at least one of a, b, and x is an integer of 1 to about 10 or a polymerized polyamine formed from a chiral diol or a cyclic ether where R 1 is a linear or branched hydrocarbon of 1 to about 10 carbon atoms; R 2 is a hydrocarbon of 1 to about 10 carbon atoms, or hydrogen when R 1 is a branched hydrocarbon; R 3 is hydrogen or a linear or branched hydrocarbon of 1 to about 10 carbon atoms; and R 4 is a linear or branched hydrocarbon of 1 to about 10 carbon atoms.
