ABSTRACT:
A golf ball including a core and a cover layer including a curing agent and a polyurea prepolymer formed from a polyisocyanate and a monodisperse telechelic polyamine having a polydispersity of from about 1.0 to about 1.3, and having the formula:in-line-formulae description="In-line Formulae" end="lead"?T-Zn-C—Y—C-Zn-Tin-line-formulae description="In-line Formulae" end="tail"?where Y is at least one molecule or mixtures of molecules having at least two independently polymerized vinyl groups, such as 1,3-divinylbenzene or 1,4-divinylbenzene; C is a hydrogenated or unsaturated block derived by anionic polymerization of at least one monomer selected from the group consisting of conjugated dienes, alkenyl-substituted aromatics, and mixtures thereof; Znis a branched or straight chain hydrocarbon connecting group which contains n=1–50 carbon atoms; and T is primary or secondary amine.
