1. 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 whereY1 is a hydrocarbon;
Y2, Y3, and Y4 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 10or a polymerized polyamine formed froma chiral diol or a cyclic ether whereR1 is a linear or branched hydrocarbon of 1 to about 10 carbon atoms;
R2 is a hydrocarbon of 1 to about 10 carbon atoms, or hydrogen when R1 is a branched hydrocarbon;
R3 is hydrogen or a linear or branched hydrocarbon of 1 to about 10 carbon atoms; and
R4 is a linear or branched hydrocarbon of 1 to about 10 carbon atoms.
